The corvette that I posted is a fellow member's ride on the (Corvette Forum). No spacer required to clear the calipers. In discussion with him he was told they were very early US Mag rims. They are very similar if not exact in appearance to the American Racing Equipment Torq Thrust "D" rims. I know early American Racing Equipment Torq Thrust Magnesium "D" rims do not have the company's information/script on the backside of the rims but they do have a label (sticker) on the inner lip of the rim. When the very early American Racing Equipment Torq Thrust Magnesium "D" rims came to market the company did not have a patent on those rims and as a result other manufacturers where making there own "version" and selling them.
