Frame Identification
Hello
I have acquired what I was told to be a mid 70's Corvette frame. The frame is stripped with the exception of front suspension. I would like to identify exactly what year frame it is. I don't see any numbers but may not be looking in the right place. Any help would be appreciated.
Thanks
Ron

Major difference is in the rear of the frame ... changed 73 to 74
with the change from chrome to plastic rear bumper.
68-73 are nearly identical.
68 is unique in that it has no diagonal braces at the rear kickups.
Here is what the rear of a 68-73 looks like:

Thanks for the replies, and the great pictures. I believe I have a 1975-77 frame. I'm putting this under a 1964 Corvette with a rusty frame. Is there a site that would tell me what changes that I'm going to have to make to the 75-77 frame for this swap?
Thanks Again

Rear frame from about #4 body mount brackets and back will need changing.
I have NO idea what a 64 frame looks like back there.
64 ... not sure if the diagonal braces added in 68 will interfere.
Lastly, the body mount bracket height and locations were changed C2 to C3.
Maybe you can find the 64 equivalent of this:

This looks like a 68-73 frame ... so the body mount bracket height is slightly off for 75.
