1963 Corvette early upper main ignition shield. Repop or Original...

[Richard G.]

How does one tell the OEM 1963 Corvette early top ignition shield from the reproductions?
I know the early shield has a less refined look with some warping in the SS sides.
Are there other methods? Rivet type or?
thanks

Rich, I Believe that the re-pops are non magnetic. originals are magnetic.

Based on what I have ON HAND, not a review of multiple examples: Original WB top is SS, sides are magnetic; rivet heads (top & ground strap) are 3/8" diameter - repro rivets are .30 diameter; WB ground strap also magnetic; "D" stamped sideways between the two rivets in the ground strap; WB spot welds exhibit variations in distance between welds from 9/16" to 1 1/2" - repros appear to be set at a predetermined 1 1/4"; ie, originals were left to the welder. Comments from others would be appreciated.
