Rallye wheel center cap screw mount holes

I believe that all the Mopar replacement caps were not threaded and came with thread cutting - not self tapping - screws. If you buy a set of real replacement screws and are careful using them the first time, and before you put them on a wheel, all will be fine. This practice stayed until at least 1984 - I bought a set of NOS caps for my 1984 Dodge Rampage with factory rallye wheels at Carlisle 2 years ago and sure enough, no threads tapped ... alternative is to run a tap through them first
