bumper mounting question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67ChevyC10Stepside · 01-27-2005, 04:27 AM

ok...i brought my bumper off my 72 gmc front clip in today to get it sanded down and painted and want to know what i need to mount it up. the truck is "supposedly" a 67 c10...i dont know if it's the original frame or not. do all the bumper brackets mount the same on the frame?? or are they all the same universal and im just stupid? i've never messed with these before so some help on what i need would be severely appreciated. also in the gmc pic there is a set of holes that isnt used...why is that?

anyone?

Inner and outer brackets for front bumper should be the same on all GMC's from 67-72.
GMC bumpers themselves are the same 67-68 and 69-72.
Chevy had different outer brackets for 71-72 IIRC.

I have a 72 GMC and all the bumper bolts are used on mine.

sorry i dont have an answer for you but i wanted to tell you that i like the way you got the grill painted .... looks sharp.

There should be a bumper bolt directly to the frame horn in those 2 lower holes. You might loosen the other bolts (not remove) until you get them all lined up. Maybe a washer between the bumper and frame horn would snug it up?

67ChevyC10Stepside · 01-27-2005, 10:30 PM

ok...the truck had a 71-72 chevy bumper on it when i get it. will the 71-72 chevy bumper brackets fit the 71-72 gmc? can someone get me a pic of how the bolts attach? what is in the bottom two holes on the gmc?

Bob Moore · 01-27-2005, 10:47 PM

The Chevy brakets probably won't work because in 71/72 Chevy put the park lights in the bumper and the holes are further out to the end of the bumper.

The lower holes use a bumper bolt through the bumper and the hole in lower part of the frame horn.

67ChevyC10Stepside · 01-27-2005, 11:02 PM

if you look in chevy duty it says 67-70 and 71-72 doesnt have GMC and chevy...so that means it should fit both right? what do these 2 little brackets attach to? the frame horns? i need someone to show me how this thing mounts up. thanks for the grille compliment BTW

The two small angle brackets attach on top of the frame horns. The holes in the bottom of the bumper bolt to the front face of the horns.

67ChevyC10Stepside · 01-27-2005, 11:22 PM

ok....wow they really dont want that sucker coming off lol. so just any old bolt will work right? just some grade 8 hex head for the inners and some carriage bolts for the rest? are all frame horns the same?

67ChevyC10Stepside · 01-28-2005, 02:08 AM

i took it out to my truck...it looks like everything is gonna line up right...on another note i scratched the hell out of it in the process...im gonna paint it on the truck probably.
