67-72 Bench Seat Bracket Differences
 

Just thought I would add a few pics of the differences in the 67-72 bench seat brackets.
They are divided by the following years:
67-68
69-70
71-72

The "floor side" of the brackets are all the same.
It's the "seat side" that is different.

I will post the pictures I have,... but I really need good clear pictures of a set of 67-68 and 69-70 seat brackets, if anyone has them.
I would like to make a FAQ on this subject.

Many people don't realize these are year specific, and don't interchange.
Please post pics of what you have,...

Re: 67-72 Bench Seat Bracket Differences
 

67-68
These are the 67-68 version.
(they are upside down from normal installation)
I have circled the main difference.
The "sheetmetal" rear seat riser.

The other difference is the adjustment arm is just a stamped metal arm.
The 69-70 and 71-72 arms have a black plastic coating on the arm, besides the plastic knob.

Re: 67-72 Bench Seat Bracket Differences
 

69-70
The 69-70 version have a tall "straight" rear seat riser.
These only work with the 69-70 seat frames.
(the 71-72 seat frame is different)
Does anyone know if these will work with the 67-68 seats?

Re: 67-72 Bench Seat Bracket Differences
 

71-72
The 71-72 seat brackets have a lower "curved" rear seat riser.
These work only with the 71-72 lower seat frames.

Re: 67-72 Bench Seat Bracket Differences
 

Thanks, definitely FAQ worthy!

Re: 67-72 Bench Seat Bracket Differences
 

Hey VA,... if you have any pics of the bucket seat mounts,... post them here, please.
Maybe the difference between the 67-72 and 73-75(?) mounts.

I have this "67-72 vs 73-75 bucket seat bracket info" from the other thread:
You "could" swap the front stands (floor mount) and use them, but they'd still be 5/8" inch taller at the front and 1/2" taller at the rear...

The bucket seat brackets are the same at the bottom rear for 69-72 and 73-up.
It's the front stands on the bottom and BOTH upper stands that are different.
The front stands on the bottom (cab floor side) are a full inch taller on the 73-up brackets.

The pieces that bolt to the seats are the same bolt pattern but different heights also. The front seat mount stand is 3 1/4" high on the 69-72 bucket mounts and 3 7/8" on the 73-up
The rear seat mount stand is 2 7/8" high on 69-72 bucket mounts and 3 3/8" on the 73-up

Again something I didn't know.

Re: 67-72 Bench Seat Bracket Differences
 

Will do. I'll take pictures later this evening or tomorrow and note the measurements on the pictures to make it easier to understand.

Re: 67-72 Bench Seat Bracket Differences
 

I thought the differences were for the full foam and spring seat bottoms. Didn't realize it was year specific.

Re: 67-72 Bench Seat Bracket Differences
 

If I'm reading that correctly, it sounds like later buckets can be bolted to the correct bucket brackets for our year of truck and installed with no drilling. If that's true, then I also hope the same is true for benches.

Re: 67-72 Bench Seat Bracket Differences
 

Yes, later bucket seats can be bolted on to the correct brackets with no drilling. 73-75 buckets almost look identical to 71-72 foam...the top foam is slightly different but the bottom foam is identical...

Not aware of any benches that bolt onto the stock bench brackets other than the benches designated for that year bracket...

Re: 67-72 Bench Seat Bracket Differences
 

Here are the mounts...I will post better close up pictures tonight with measurements added but this should help people identify the brackets if they see them for sale or on a set of seats.

Re: 67-72 Bench Seat Bracket Differences
 

I agree. Someone may be doing a year correct restoration and could use this info. I wasn't aware of the differences either.

Re: 67-72 Bench Seat Bracket Differences
 

This isn't neccessarily for "correct restorations".
It matters for any 67-72 truck when replacing the seat brackets.
They physically don't interchange unless paired up to the correct seat.

I see them for sale all the time in the classifieds,... and no one specifies which year they are for.
Just 67-72.
I found out when I bought the incorrect set for my '69.

Re: 67-72 Bench Seat Bracket Differences
 

good thread Keith

Re: 67-72 Bench Seat Bracket Differences
 

Does anyone have a good clear picture of the 67-68 bench seat mounts?

Also a BIG thanks to VA72C10 for the excellent bucket seat pics!

We may have to add "Utility Buckets" to this thread,... if anyone has good pics.

Re: 67-72 Bench Seat Bracket Differences
 

I can snap pics of mine (1967) just let me know what to look at and what to take pics of. My brackets are still on the seat which is setting in the cab not installed so I can remove it easily.

Re: 67-72 Bench Seat Bracket Differences
 

I'll PM you my email address.

Re: 67-72 Bench Seat Bracket Differences
 

I just need clear upright pics of the 67-68 seat brackets from the side and front.
Prefer off the truck seat.

Re: 67-72 Bench Seat Bracket Differences
 

Thanks to member fastcam1,... here's a better picture of the 67-68 seat brackets.
I circled the rear seat riser that is a stamped sheetmetal bracket.
(different than the 69-70 or 71-72 brackets)

Re: 67-72 Bench Seat Bracket Differences
 

I see fastcam beat me to it, I'm at work for a couple more hrs. Thanks for posting the differences Keith. There are so many little differences on these trucks that most people don't know about, including me. I learned a lot of them so far and many the hard way.

Re: 67-72 Bench Seat Bracket Differences
 

Again this Site has the Greatest detailed year-specific info. Much appreciated and subscribed!

Re: 67-72 Bench Seat Bracket Differences
 

DOes anyone have a picture of the passenger side track for a bench? Mine is missing the piece that keeps the seat from sliding back and forth on that side.

Re: 67-72 Bench Seat Bracket Differences
 

Great info! I started a thread on 67 info and will include the link so I can read it later!

Re: 67-72 Bench Seat Bracket Differences
 

Does someone have a pic of the spring seat bottom vs. the full foam bottom? Were the spring seat versions common to particular years?

Here are some pics from a 73-74 GMC Data Book and a few pics of my bench seat bottoms from a 70 and 73 Sierra Grande.

Subscribed! Thanks for the info.

Re: 67-72 Bench Seat Bracket Differences
 

Hey MusicMan, those last two photos of your 70 & 73, is that the "full foam bottom" version? This is what my frame looks like. Thanks!

Yes Steve. I believe the Sierra Grande's came factory with Full Foam and that is the spring pattern for them.

Re: 67-72 Bench Seat Bracket Differences
 

Thanks MusicMan. When replacing my seat foam, do I have to buy seat frame year specific foam? What I mean is, 71-72 seat frames are the same but will any year foam work as long as it is a "full foam bottom"?

67-68 Suburban

Re: 67-72 Bench Seat Bracket Differences
 

This might be of interest. it seems that seat from C-40 and larger trucks 73 and newer use earlier seats and brackets. Those trucks do not have the raised floors to clear the gas tanks. We replaced the old seat brackets whick looked like the 69-70 style (if I remeber correctly) with some from an 84 and installed the seat in the 84. That rtells me there is interchangability to the seat frames.

Re: 67-72 Bench Seat Bracket Differences
 

I was just on the Classic Industries website and they list replacement seat foam for the '67-'68 for $299.99 and for the '69-'72 for $470.00 What gives? Is there a difference in the foam between these years?
