Interchangable sport bumpers - The 1947 - Present Chevrolet & GMC Truck Message Board Network

killthewabbit · 10-02-2012, 10:23 PM

I've been looking for a driver quality sport bumper for my 85 swb for a while now. A buddy offered to hook me up with a sport bumper and brackets from his 86 Blazer. I've read the Blazer/Suburban inner brackets won't work, but I wanted to confirm the outers and the bumper will fit just like the sport bumper should.

Anybody have knowledge on the feasibility of this?

bigblock73 · 10-02-2012, 10:51 PM

Bumpers will be the same, so will the outer brackets.

Done this on my truck before.

I wish I could find one.

Where have you looked? There are a lot of them out there on old Burbs and Blazers.

mopar346 · 10-03-2012, 11:18 AM

Are you referring to the rear car like bumper? I have nothing to add just trying to learn the verbage.

killthewabbit · 10-03-2012, 11:01 PM

Thanks for the help, Jeff. I'm gonna try to score the bumper and outer brackets tomorrow. Now I just need to run across some inner brackets.

You really don't need the inners, just run the outers until you find them...it will be plenty sturdy.

killthewabbit · 10-04-2012, 11:48 AM

Didn't know that. Thanks! I'm gonna go get it today if all goes as planned.

bigblock73 · 10-04-2012, 12:29 PM

dont forget the license plate box, lamp and wiring...

Mine was factory equipped

one of 5 options the truck has.

killthewabbit · 10-05-2012, 12:26 PM

All didn't go as planned, so I didn't get it. With any luck it will still be available when I get the chance

77c10 · 10-07-2012, 07:01 AM

I am looking to do the same on my 77. Please let me know how it goes. I am not far from you.

killthewabbit · 10-08-2012, 11:26 PM

Not far at all! I took a day off today and pulled it. It was a pita to get off like pretty much any part from a 30 year old truck, but I got it home, stripped down, cleaned up, and washed off. I need to go buy some new bumper bolts and bracket bolts, then I'll work on swapping out my step bumper.

Anybody know what size the bumper carriage bolts are offhand? I was gonna score some new ones off ebay unless someone knows a better (non-LMC) source.

KrazyRay · 10-11-2012, 08:55 PM

Not to hijack, but are all 73-87 pickup sport bumpers the same?
I believe the carriage bolts are 1/2".

No.
Two styles.
73-80
81-87

**1774btcrew** · 10-11-2012, 08:58 PM

73-80 are the same then 81 and up. In my opinion just the outers are not good enough. I have done this on my 85 and if you step on the rear bumper at all with just the outers it moves downward

Are 73-80 Blazer bumpers the same as 73-80 pickups?

Yes.

KrazyRay · 10-11-2012, 10:37 PM

Thanks Keith. I was about to pull one from a 87 Blazer for my 73 pickup. I will start searching the older Blazers and Burbs.

If you find a 73-80 blazer or burb,... grab the outer brackets also.
They are the same as the pickups.

The inner brackets are different.
You will need "pickup specific" inner brackets.

kalbert · 10-11-2012, 10:43 PM

Out of pure curiosity, what's different about the pickup brackets vs the Blazer/burban ones? Is it something to do with the fuel tank vs spare tire or?

killthewabbit · 10-13-2012, 08:39 AM

The inner Blazer brackets are really short and stubby and L-shaped. Here's a pic:

KrazyRay · 10-13-2012, 11:14 AM

Looks like you have a nice bumper. Can you post some pics of it installed?

killthewabbit · 10-13-2012, 11:47 PM

Sure, when I get around to installing it. I need to round up some new frame bolts and some carriage bolts.
