8 1/4" rear changeover suspension parts

changed from 7 1/4" to 8 1/4" rear. Need ubolts, shock plates, backing plates, correct driveshaft lenght. Non-performance.

May want to start a wanted add, There is a chart in the how to section with the drive shaft lengths.

As for the shock plates, the 7 1/4 ones can work, all you have to do is drill your holes on the plate about another 1/4'' or so, in other words make them oblong. Drill towards the outside of the plate. That is the only difference between plates.
As for the drive shaft, makes a difference on which trans you have, they are not all the same lenght.
