We currently have a 70 4 door Delta 88. Put impala bumpers (unsure of year) on the front and back of it, hardnosed. Replaced all the body mounts with 3/4 inch all thread. Welded suspension solid, front and rear. Put in a Chevy 350/350 combo into it. Great front end car thanks to the "K" frame up front. We welded any frame seams or joints that we could get welding rod too. After we ran it in a few races the frame right before the firewall literally collapsed into itself. After a lot of torching and pulling we got it out and started plating our frame up front with 1/2 inch plate. Really anywhere that we thought might bend. Rules are pretty lax around here so as soon as I show them the large scar on my hand from getting my hand pinned by the steering wheel to the impact cage. Our impact cage is just 4/4 steel all the way around in a big square from between the doors to the dash. Universal joint in the stripped steering column. Welded rear end to make it a Posi. Weld all the body metal seams you can possibly get to. We tucked the rear quarterpanels to the trunk seam and welded. Made our rear real solid. Just weld away and you can't go wrong.
Whats the general concensus on how far a 73 buick trunk should be tucked also could i just cut the lid off and have same effect as tucking also i got rot where my batt holder was but its on the fender inner only not on core support should i worry adout it or not i was planning on wrapping floppy fender edges under core and welding em up, good, bad idea, onto the trunk again i pulled the pucks on the back four body mounts and sucked the trunk floor down with 3/4inch allthread i cut the pan out where the two humps are on the cross member behind the bumper so it set flush u think thatll really matter, where they pop through the floor i was probably gonna weld it to the floor anyway, i replaced the core bolts too inever change the cab bolts never had a need to, and swapped the front bumper and brakets also to a 76 olds 98 its what i had and better than a 73 bumper and brackets, my assend is super low any suggestions tried picking assend up and welded rebar to extended springs and didnt do anything may put bigger springs in. Also i never welded spider gears but i want to this year anyone got a pic or drawing of what need to be welded
No pics. Just use a c clamp and heat it up as you squeeze the clamp right behind the bumper bracket. Or you can just bend the top down with a big cresent. Either way, I would jack up the car at rear bumper while you do this just to have pressure in the right direction. Do NOT cut the c channel.
im building a 1972 buick 225 and would like to know some tips for building this car the rules r kinda stock but allowed to swap bumpers and weld hood and doors fully any advise would be great[/quote Refer to my post on page one.

Hard nosing that monte bumper is the way to go, it will however make the car bend at the firewall as opposed to the a-arms. Leave the stock original bumper on the rear. As stated above me, it will help it roll and pack better. You've already addressed the weakest part of the car (the core support) by upgrading to a 73 caprice clip. It will however, be a shoehorn fit between the frame rails to instal properly.

I was thinking of taking a 72 caprice and removing the trunk lid, flipping it upside down and putting it back in the trunk and bolting it to the floor, i was curious if anyone tried this before i thought of it, possibly doing it and beating the quarters down good and deep so it would pack into itself.
Seen it done, never tried it. I think it's a good idea to try. Be better if you were allowed to weld trunk lid seams with it flipped and exposed maybe you could call it an 'outside' seam. That would stiffen up that trunk lid to help it roll and pack. It's important on these cars and 4-6 sedans also to get the sheet metal to pack in to help you achieve a good roll. I don't claim to be an expert at it, had some work and some didn't work.
