I sure would like to know where I could find a set of those.

[gostranger]

very cool information!!!!

[aerotruk63]

Since the truck line shared a lot with the passenger car line, did the station wagons of the past have this type of set-up?


They look like 3/8" fine thread. A type of slot bolt. Could easily be fabricated.
On the Chevy's do they use a 3/8" or 7/16" carriage bolt with a wingnut?

This kit includes the factory-correct 2nd & 3rd row seat mouting plates for the '60-'66 Chevy/GMC Suburbans. This kit includes 12 mounting plates and factory-correct mounting hardware, as would have been installed for 2nd & 3rd row seat configurations in the Suburban Carryalls.

Seems the description omits the existance of tracks found in the 63-66 GMC's.

so you can use both seats in both positions the holes are the same.

[dthela]

you can use electrical "unistrut" for track also. cheap and has threaded nuts with springs that lock in the tracks. Available at home depot.

found a full set of eddie bauer leather power expedition seats on craigs list. $250! 3rd row has power fold down 60/40. front buckets are power, 2nd row folds down also

[aerotruk63]

Did you recess the electrical tracks into the floor?

The guy I'm trying to find original 63-66 GMC seats for would like to have the drivers and a reversed 2nd row 39" seat touching back to back and the 3rd. row 56" at the rear position. Give the rear area a limo feel. We joked about installing an original wheel and tire with a hubcab with a round plexiglass top to use as a coffee table between the two rear seats.Your track idea might help out in this application.

Because I have a 65 suburban with barn doors I want to put two short 2nd row seats one behind the other so the seating can be accessed from the rear. Is this even possible, I don't see that type of arrangment in any of the diagrams.

Yes, if you have two of the 2nd row seats you can accomplish this. The mounting should be the same since the 3rd row seat is able to be bolted in the 2nd row position.

[dthela]

don't think there would be enough leg room. lay them in loose to try it. You could always use the unistrut in the original slots too. they do make assorted pipe clamps and angles that work with the unistrut system

I was at a yard this week that had dozens of old school bus seats. I measured the base and their 39" approximately wide. Same width as the smaller rear seat in the rear or the drivers seat. Cheap to buy, easy to modify, if your not going for original. Now on this originality thing, I can't see GM opting to have suburban seats made in house and these seats sure are fabricated in the same manner as school bus seats. So I sent off an email to Blue Bird one of the oldest school bus manufactures in the States. Maybe they'll respond with who supplied them seats back in the early sixties.

rossboss saw a school bus picture of a suburban set up that way.

1963 GMC with tracks.

I was told that GMC had the sliding tracks and Chev the bolt openings. But I also know that they used whatever was at hand when building our trucks. I have seen burbs that had the truck style solid metal steel body mounts under the core support, instead of the vulcanized rubber ones. I would bet that there are GMC's with the bolts. Think about it, back then no one would question how their truck came from the factory as long as it had the 2 or 3 rows you ordered. It's only because of our addiction to these super cool trucks that we want to learn everything there is possibly to know. Look through the GM accessory booklet and see if, ordering with sliders or bolts was an option. Maybe it was

Did the 63-66 GMC rear seat backs come clad in vinyl instead of the painted ribbed steel? Seems the two front seats are steel backed however.

[dthela]

GMC's had bolts into holes in floor, chevy had tracks. I never used the unistrut, only a suggestion. I have seats out of a eddie bauer expedition buckets front, buckets center and rear 60/40 full width. left buckets in the s4econd row to the sides so i have a center "hallway", easier than tilting seats forward. I was howevwer going to use Caravan seats. But when the set of leather electric came up for $250 I couldn't resist!

Again, read the thread's progression before commenting. You are partly correct and partly wrong.

I'm pretty sure that no years had vinyl backed seats.

[aerotruk63]

The picture above with the vinyl covered back is from a 1966 GMC out of New York State and Bills Truck Shop in Ontario has a 64 GMC for parts, out of California, and it had a Vinyl back on it. Need to find another source. This is so interesting how GMC was different than Chevrolet in the seats.

[padresag]

you more than likely got more for the buck with GMC than you did with Chevrolet. like the guard under the rad

Seems that way doesn't it Ron.

had one of these sticking out from the base of the back seat that was stuck in the back of my suburban. the seat had come out of a panel and had been screwed into the floor

Here is the mounting bolt/spacer/wingnut on my 1961 GMC seats.
Also the seat cushion for your bum, pops out rather easy due to this
angled frame/detent/whatever you'd like to call it. These seats are heavy
so anything to lessen the load for removal
