So here is the situation. I have a 1969 4 speed 350/350 convertible(see pic), and recently pulled the engine and transmission in order to have them worked on and it was revealed that there was FRAME DAMAGE!!!! It is a beautiful car, but the damage is worrisome as it was not previously disclosed or noticeable that there was any prior damage.
So I would like to find a replacement rolling chasis or frame, and would like to know what years would fit a 1969 small block convertible?
Will a 1968 small block frame fit the 69?
Will a coupe frame fit a convertible frame?
Any other issues that you could foresee?
Regards,
John

There are small malformations and waves near the rear engine compartment closest to the firewall. They were covered up by the motor and now that its out of the vette they are noticable.
Hi John,
Car looks very nice in the picture!
I realize you're shocked and concerned about this frame discovery.
But as Fred and Mick said it's really impossible to get an understanding of the situation and offer some meaningful advice without some pictures of the area that concerns you.
There's no difference between a coupe or convertible frame, and only slight differences between a 68 and 69 frame.
So, post some pics and maybe it's not too bad.

We need pics. The C3 frames often tend to look a bit crude in certain areas. Possibly what you are seeing is considered normal by folks who have more experience with these frames.

Yup, photos of the frame damage or photos of the real car, the one you posted looks to nice for us to believe it has significant frame damage .
So many of our cars got sideways at one time or another. And maybe were beat on?
With modern frame straightening machines, they can get frames straighter than factory specs.
Good luck.
Check out my bats 69 build thread for pictures,
My frame had rust holes, not bad but holes I opted to get a 68 chassis modded, mod it a bit more and swap them out,
But I have had many vettes, one had frame issues, it wasn't something that would be a safety issue it just was a hire out from the front end being able to get aligned, a special A arm part fixed that,
If my car didn't have holes in the frame and could be aligned and didn't crab down the road, if the wheel well spacing, gaps etc were not too bad I wouldn't get too worried about it,
I agree some picture are needed, my tech showed my both on my 68 chassis and his 79 the ugly things done when these cars are built, you might be thinking something normal is damage...it's not like you had any signs of it before yanking the engine did you?
notice the top corner of the frame. see the buckled portion above the corner. These were taken today off my gopro and a picture from the paused frame, sorry for the blurry pic. will upload from camera next visit to the car.

The damage looks to have been on the L/F crossmember. Looks like the left frame rail was pushed inward toward the centerline of the chassis and was pulled back out by a frame guy with either not enough experience or no idea of how to walk a frame back out after its hit. If the car tracks well and it aligns well, Then an experienced frame guy can repair the repair for you so it would look factory. Which would be what I would do. Or just replace the frame and be ready for all the mission creep that you will encounter while doing so. Not a bad thing but can be expensive.
This looks like the area the OP is writing about.

I would measure the distance between the axle centers to make sure they are even and square, then wire brush the area to check for cracks. If they check out okay, paint it up and call it good.
Whoever pulled the frame left an ugly wrinkle , Which is what the OP is concerned about. And I agree , It looks bad and can hurt him at resale time. Thats the kind of thing happens when a frame guy pulls a frame rail cold instead of using a little heat along will a pull in the right strategic place and angle. Im over simplifying but you get the picture.

John the pictures are not really crisp enough for me so I will bow to those who can see better. Your questions, that no body seemed to answer are: A small block frame fits a 69. A 68 frame has no rear bracing for the up kick rails. They can be added thought. A 4spd frame is different from auto as far as the #2 cross member is concerned. I believe 70-73 will fit but the ride height is a little different, but can also be adjusted. There can be many small issues but it always comes back to time and money.
This should get everyone talking.

Take your car to a reputable frame shop and ask them to provide an estimate for making a 'servicible' repair. If you aren't going for an NCRS ribbon, just get it fixed....WELL...and move on. Don't assume that you have to replace the frame (you won't), nor that it will take big buck$ to repair. A good shop can do wonders for resonable funds.

I can't really see anything in the pics but if there is a minor bend/dent there then this is the way to proceed.
