Question about Torque Thrust Wheels

[impala L78]

Jason - Do the caps push in from the front (plastic) or the rear(metal). If from the front, yes they are 1970's vintage. I have a set of American Spirit wheels on my corvette that has the same type of push in cap. I also have an original American Wheel catalog from the 1970's, and it lists the push in type caps for some wheels. But it does say to supply them until they run out and then issue the screw in and also the push-in from the rear type caps (metal). I have been successful getting replacement caps from a guy that is now located in California. He sometimes has ADs in Hemmings. If you wish, I can get you his address.
