I had the ProStar recommended optional SCT410.3 body mounts. However, these required extensive modification with my dremel to fit the ET410 Kevlar shock towers. The pictures my friend sent me showed different body mounts – most likely Associated ones. They looked to be a direct fit on the rear and requiring less modification on the front. I’d check with ProStar and find out what these are and purchase those body mounts, unless you are a Tekno purist. But the SCT410.3 body mounts do work but the rear mounts after modification end up slightly wider spaced than the stock ones. With the Silverado Truck body I use for SCT, I will have to be creative to find a way to secure that body with a body clips - but its doable. However, wider spacing between the rear body mounts may not work with your style SCT body.
