Because in the end the weak link is still the GEARS , see the picture above . I definately say a prayer and cross my fingers every time I leave the burnout box and stage.............8 3/4, stock caps, backbrace and 30 spline axles and at 3200 lbs to boot however, no dana under my car and I should be at or around 3000 lbs. soon........

I have a narrowing jig to do just about any of the common axle/end combinations. I too used a dana from a truck and other than the tubes being thicker they are great. If it is leafsprung you may need 3 1/8" u-bolts and modify your lower shock mount/sping plate holes and new perches. hope this helps. Beep
