Stage 8 (http://www.stage8.com/Automotive.htm#) Has any one tried these? Good or bad experiences? For $50 a set I'd like to know that they actually work....

My dad has used these for years on his '69 nova and thay seem to work really good. since for some reason they will not fit on his new BB i now have them on my elky.

Got a buddy that has 'em...he swears by them...two years now and no loose bolts!
