Default chassis modification possibilities need advice

around march i plan on picking up my 1977 from my parents house and bringing it to my new garage. ill be pulling the body off the chassis, and then the chopping and welding can begin.

same old achiles heel frame rot right in front of the rear wheels, i have the replacement sections and cross member, with the inner sleeve.

i was thinking about rather than bolting the birdcage back onto the chassis the conventional way, maybe welding it directly to the chassis, no bushings in between, just pretty much making this a primitive unibody chassis

i know its gonna be a rough ride and it would be very inconvenient if the body ever had to be pulled from the frame again, this is just a possibility and was wondering if anyone had an opinion on the matter or have done this before.

STOP you thinking process...thinking that welding the birdcage to the frame is a good idea is not even close to reality.

The frame and birdcage need to be able to be separated for service operations...such as fuel line or future rust repairs.

Repair all of your issues and re-assemble the car back as per the assembly manual. because if I got a Corvette in my shop that has been welded together...I would be spitting out words that I honestly believe would make a sailor blush....and could not type in good conscience.

^ I agree. There is no reason or benefit to do as you are thinking, it will just be problematic down the road. What's wrong with mounting some bushings and bolting it together the way it's suppose to be?

...and, from experience, I'd recommend checking around for a new frame. It is often times, cheaper, easier, faster, etc. etc. etc. to just use another frame rather then welding up one that is rotted. I got my absolutely perfect beautiful frame for $500. This was the same cost just for the repair section to fix mine, not including my own labor, jigging it to keep straight, and any other problems that may have arose. I spent the time gained to seam weld and do other modifications on the new frame per the chevy power book.

G'luck

Search the forum for frame modifications, or google for the chevy power manual. There are several modifications to the frame to make it nice and tight. As I had mentioned, and a few others in the book are;

- Finish seam welding the entire frame. It was originally "stitch" welded.
- Gusseting the control arm mounts
- Reinforcing the diff. crossmember hats
- Welding plates over certain unnecessary holes

etc. etc. etc.

It shouldn't be hard to find.
