Raising partial VIN after block is decked

[iluv69s]

I remember a few years ago a 67 vette that had labrotory documentation that the original VINs on the block and frame had not been restamped over. They apparently did some acid etching type test. I believe it was an L-88 or L-89 car. I did a search, but cannot find it.
I also had contacted a scientist here in Pa at one point about ten years ago that did such tests. I will have to look for his number. I believe his last name was Klauser..??
If I come up with anything, I will post.

That would be great! My 67 327 was decked waaaaaay back in 74 and is the original motor to my 67 Nova SS. Would love to bring it up to see. I have a the pop to the car that would help.
