I have them on my stock car. Allstar also makes them. I have only seen them available for the G body metric and the pinto as far as stock style spindles. I don't know how the dimensions of either the metric or pinto compare to the a body spindles to know if they would fit or could be modified to fit. For what it's worth the hubs spin noticeably more free than without braring spacers when adjusted properly. Recommended to have .001" - .002" preload If I remember correctly. They also offer low drag seals and REM finish bearings. I put a low drag seal on one side and a used stock rubber seal on the other and the difference was surprisingly noticeable when spinning by hand. Does all this add up to a reduction in lap times? I don't know. Probably not. Lol
