I have never seen an original filter for sale but you never know. If anyone has any different information on these filters let me know. This is the standard we are currently using when judging 90-91 ZR-1.

Dave,

You are right on the money. My car was judged in NJ with a 970C service replacement filter. I was hit for a few points, can't say exactly until I get my sheets. I have never seen a real 970 filter, except there is a copy of a label in the NCRS Judging guide. If you could find a real one and get accurate duplicates silk screened you could for sure sell them.
