1982 CE Shim marks

[David K.]

Can anyone tell me what the shim marks look like on a 1982 Collectors Edition?

I believe I can still see them on the frame of my wife's car but they appear to be a numerial rather than hash marks. Is this coreect? Are they suppose to be right side up or upside down on the frame? Also, if no shims were needed did they leave it blank or mark a "0" (zero)?

David,

You are correct, the shim count on the frame rail of her 82 would have been a numerical character, not hash marks as used on older models.

The characters were written with the chassis in it's upright position so the shim count characters would read correctly in that position.

There were two methods used when no shim was required at a body mount location. One was to leave no mark at all and the other was to indicate no shim with a zero. The zero was prefered and eventually became (supposedly) the accepted method.

David:

We've seen among those late model C3s, digits written in colors including yellow, green and red. Typically we see one color used on one side while another color used on the other...don't recall any specific pattern. Slashes were last used in 1969. Also, while difficult to restore precisely, tape can be seen in place that was used to hold the shim pack in place until the body was lowerered. check your 82 for colors used if enough remains for detection.

Where are these marks located and what do they look like. A picture would be very helpful. Also what years have them. Thank You. Curt.

Curtis,

I just happen to have a good pic of a new Corvette frame on the St Louis assy line that shows the "shim count" on the side of the frame rail near the body mount. It's the hand written "2", indicating 2 shims at that location. The great big orange contraption being removed from the frame is the fixture that measures the frame and it's mount pad heights.
