long wheel studs for factory discs
15 years ago I switched my 70 Duster from aluminum slots to Convo pros and was told that I needed longer studs because the stock ones did not come through the open lugs by our local track tech inspector. There was nothing available anywhere so I removed a stud and took it to a machine shop that had the tooling to copy the shank with a 3 inch threaded stud.I had 15 made for 120 dollars 10 plus spares.
