bumper - bumper questions - Page 2 32688910


and btw this isnt my picture


but i just have the 2 end pieces and i am going to shorten it inward

(if you look at the 2 pieces from the top i am going to take about 2 inches out of the top and weld the 2 pieces back together and put a plate under neath and weld it in for extra strength and that will shorten it just how i want it on my 77 malibu

I'll try to get some pics up if I get time. The frames are the same, but you would be surprised at the difference in shock mounts. To do the tuck, you might end up having to find a complete 73 front bumper, shocks, & all of that. It ain't happening on a later model without some good ingenuity.

I'm doing front and back on my 77 cutlass. I'm going with fiberglass instead of chrome because mine were gone(front), rusted and bent(rear). I'm keeping the inner support structure...cuz I'm chicken, I drilled out the bumper shocks (be careful, they aren't under alot of pressure, but they will spray oil). I plan to "adjust" them in with a sledge, then redrill through both the outer and inner shock and put a bolt in it to hold it. I'll post some pics when I do it.

Not all 73-77's A-Bodies are 3rd Generation. The 73-77 Monte is 2nd Generation and the 73-77 El Camino is 4th Generation. Should be renamed "The Colonnade A-Body Site/Forum"...

Just sayin.

77malibu are you keeping part of the inner bumper section? I'm just curious since I've always been under the impression that you could get rid of all of the internal parts and just use the bumper itself. Would a pair of brackets that mount to the bumper work just as well?

yeah you can use a pair of brackets but you cant really remove the whole shocks and bolt it directly to the frame cuz it would look like a dork fish with an overbite (if you have ever watched blue collar comedy) lol but how would you bolt the shocks directly to the bumper itself?
the only thing i can think of is to do what somebody did on the 76 laguna earlier in this thread and drill holes in the bumper and put bolts through it but i only want my bumper sunk in like 2 inches so i dont want to bolt it directly to the shocks
i am just using the end pieces because it shaves weight and i can eventually cut 2 inches out of the inner structure pieces to whatever length i need them at to either stretch out my bumper ,or sink it in (which is what i am doing)

Just sayin.

actually, the Monte and Grand Prix weren't even considered to be "A" bodies withing GM- they were designated either or "A special" bodies (68-72 GP and 70-72 MC) or "G" bodies (73-77_..
but that's kind of outside the scope of a thread about tucking in bumpers..

this is what i am talking about you could do if you are just wanting to bolt the bumper to the shocks/frame

I was just figuring that you remove the shocks and inner bumper assembly and make a bracket to mount the bumper to.

OK SO I OFFICIALLY JUST SUNK IN MY FRONT BUMPER
took some careful maneuvering and a lot of cutting but i got it and it works and it looks really good
i only sunk it in an inch and a half but its good for right now
the best part is if i want to sink it in any farther i could do that if i wanted to or if i want it back to stock or even all the way sunk in flush with the headlights lmao!
i didnt drill in the shocks/ or mess with them in any way, the only way i did it was just cutting up the frame inside the bumper and it also took off a ton of weight!!! the technique i used might even work for the rear bumper to bolt directly up to the bumper shocks


i am so happy with how it turned out Thumbs up

the only thing is its hard to explain and i cant take pictures so i really cant help any of you do it unless i get ahold of a camera

NO CAMERA???!!!!! Dang it. So how did you cut the bumper frame & get it to mount up? Did you have to weld or is there some other mounting point that brings it in? I ask because I have thought this over for a while & can't seem to figure it out without going to 73 mounts or welding. I have an idea, but I'm thinking about cutting the bumper frame, flipping the mounting points, & re-attaching. Still don't know how that would turn out though or if it's possible.

no rago there is no welding involved cus i have no access to a welder lol!

alright ill try to do my best at explaining and use this picture to help

bumper - bumper questions - Page 2 32688911

alright everything in the black i cut out notice i still left the 2 holes on each end where the bumper frame bolts to the actual bumper shocks so you will have 4 bolts holding the bumper onto the car all together, and what i did was i slipped both of the ends over the inside of the bumper shocks normally they bolt to the outside and i put a bolt though with a spacer inbetween cut to the desired length i wanted it at and attached the bumper to the 2 end pieces of the bumper frame then tightened the bolts with the spacers between them and now it looks professional all i need to do now is take everything back apart and paint it again because the paint got all messed up, the best part it supports my weight too and will support yours too rago lol!

let me know if there is something you dont understand i tried my best to help you lol

and before you do any cutting make sure you leave enough places to bolt the bumper to the bumper frame lol i have 4 bolts on each side holding the bumper frame pieces to the bumper itself then 4 bolts total holding the whole bumper to the car
