I am building a 76 Pontiac for a local show in July and I am unsure how I want to do my front bumper and brackets. I have read some no so good things about the Pontiac brackets. My options would consist of 74-76 Olds brackets slid back as far as I could get them, shocks collapsed and welded, bracket welded solid to the frame or hardnose the bumper to the frame and still use the bracket.
My only real fear is being able to get a core support in it after I hard nose. All my current measurements tell me that it’s going to be very, very tight.
What’s everyone’s preference?

I never had an issue with the Pontiac brackets. Front or rear olds brackets? the 74-76 style? I have hardnosed and run 76 olds front brackets/shocks on 76 gm frames. Hardnosing seems to put more pressure on the holes in the frame between core support and engine crossmember. Bumper seems to be much more secure though. Brackets, and specifically the shocks in those brackets, I have had many many problems trying to get decent welds on them to retain the bumper. Maybe it's just me though. They do give you some bumper height and in my case, they seem to promote the car bending at the firewall. I had no problem with my core support after hardnosing but it is close. Would you be allowed to weld bracket over the hole in the frame if you didn't hardnose the bumper?

My brackets have to be mounted where they were from the factory, other than being able to slide them back. |

I think in that case, I would prefer hardnosing and the bracket over using the shocks and bracket, as long as I could the front bumper height I needed.
