i was lucky enough to get ahold of some trust/greddy axle backs on ebay a week ago, and they arrived today. i began mounting them up to the rear y pipe when i realized that the flanges are like 30 degrees off from the flanges on the axle back. i am very confused, i thought these should mount right up. anybody know what my problem is? thanks
