Default 1970 Frame Question

I am buying a 1970 Corvette. It is definitely a daily driver. There is wear on the seats, the paint is OK, with a few quarter sized chips on the convertible deck lid. The engine exhaust looks OK and there is the usual dirt, grease, rust in the engine compartment.
The frame looks brand new. Even the bolts are under the car are very shiny new! This seems strange to me. Why go all through the trouble to replace the frame and not take care of the other stuff?
I am buying the car from an elderly guy that flips cars for a hobby. He bought the car from an estate of an deceased individual in Missouri. The family did not know anything about the car other than they wanted to sell it. The car had obviously been sitting a long time judging by all the dust on it.
Anyone have ideas on why the frame would be replaced without doing other work on the car? My thought is that the owner may have started a frame off restoration and got ill so he put it back together. Any other thoughts?
Also, Is the VIN stamped on the frame? If so, where would I find it?

Hi gr8,
I'd say there are lots of reasons (not all good) for needing to replace the frame on a Corvette.
There could be good reasons only the frame was restored too as you've surmised.
Yes, the VIN of the car that the frame was originally used for was stamped in the frame in 2 places.
The first on the frame rail about where the driver's left hip is is impossible to see with the body in place.
The second on the left frame rail just forward of the #4 body mount is sometimes visible.
Take a peek…. you never know what you might find.
Regards,
Alan

Look in the area above the shim count.


Use a small mirror and light.

Hi gr8,
Sorry!
I thought you'd be able to tell from the first picture.
On the top surface of the frame towards the very rear of the left side rear wheel-well.
Regards,
Alan

Oops, I forgot my server at work filters out all the pictures. I will look at it when I get home.
Thanks!

Where is the first? The "drive's left hip" is not a clear location for me. Just trying to locate my own frame vin. The one by mount 4 is not clear.

Hi AT,
The first VIN stamp is typically in this area.
Regards,
Alan



The machine used was powerful enough to but a small 'recess' in the frame's surface where the stamp was done.

Also consider the possibility that the birdcage and frame were both badly rusted, and only the frame (being easier to replace than the birdcage) was replaced. Check carefully for rust!

That's actually a very good point.
