The frame around the sway bar support is very flimsy. If you want immediate reaction from your sway bar this area need to be reinforced and the frame completed by boxing it.
Last winter I installed gussets from the underside and welded them in from the bottom.
To do the job properly the rad and support must be taken out and welding must take place from the top.
There is also a ugly hole in the frame right in a crital place. The frame is also missing the inside plate so you have a very weak C section that flexes whenever the sway bar needs to transfer load from one wheel to the other.
The first think I did was weld up the existing pieces of the frame along with welding the top side of the gusset I previously put in .
This is the welded gusset, the hole filled in and tying everything I could together’

The next thing I did was take 1/8th material and make a plate and form it to fill in the rest of the frame to complete a rectangular section. I then welded this plate in.

I did both side last night and slapped a bit of primer on. I will lightly grind the welds tonight and finish painting. I will spray undercoating on the inside of the new frame rail and paint the outside gloss black.
This is recommended in the Chevy power manual on racing a older C3 corvette.

I know Marck but even if I can plant an idea in one guys head it is worth it. I don't drop by here very often but I do like to run some of my latest projects past these guys. Maybe something with stick.
I don't notice you posting anything here either, but then again I don't check very often
Guys how about a good 5 speed overdrive transmission for under $500?????????????
 
Sorry if you feel unappreciated, norval.

I read every post and I'm always amazed but I rarely, if ever, reply.
You see, I don't like "cheerleading" and I can't ask intelligent questions since I've never built anything like your fantastic Vette. I won't ask dumb questions so what would I say? ;shrug

Keep em coming, as Diemaker I can appreciate the ammount of work and thought that goes into your mods. I just don't need to comment; but if I did it would be how amazing your car is. ;)

I would like a ride someday.
 
Excellent post! You & TT are far ahead of me in your engineering and fabrication techniques. Like the others, I may not reply but I enjoy seeing (and envying) your work.

Haven't been checking all the projects in C1/C2 have you? ;)

What projects? Sounds interesting, I was commenting on norval's posts, when I saw this posts I checked his other topic and the first couple had 0 replies and they are all in C3.
 
Thanks for posting this useful info.... I am in the midst of restoring my 69 and any and all tips are appreciated!

One more tip I have posted before. Put carb studs in the floor for the seats. A long carb stud is 5/16 coarse on one end that screws into the floor and 5/16 fine on the top for fastening the seat down. It really makes installing and removing the seats a 2 minute deal.
Any 5/16th stud would do, carb studs are just easy to get.
