There is thought from some within NCRS that there was an assembly line oil filter and there was a service oil filter. In an effort to save money, assembly line oil filters were 'unadorned' whereas service filters were more 'adorned' or, colorful.

It does, to me, make sense this could be true but only three data points are known and all three are Camaros. There is rumor of an original 69 Corvette filter that is out there but not found. Hopefully, that (find) will soon take place and there will be a fourth data point along with a different model.

I thought I knew everything about 69 oil filters but, as typical, I don't know much. Every answered question leads to more unanswered ones.

The research continues... </div></div>

I understood that in late 1970 the service filter with the color that was sold to the customer became the filter used on the line. As to the black screened filters I think your best shot would be to try to replicate one from an existing NOS embossed unit.

Caudill's restorations screened repops of the black and white filter about 15 years ago but the bottom base of the filter was not embossed which still made them technically incorrect.
