Here's a list of parts you need to do the SYE/CV rear driveshaft modification (not necessarily these exact brands, but since you've got RE parts anyway). If you shop around, you might find these parts cheaper, and there's other companies that make these too (like the adjustable upper control arms).
Adjustable rear upper control arms (so you can adjust your rear pinion angle when you install the SYE and CV driveshaft)
Rear track bar bracket to compensate for the rotated rear axle. Do you also have an adjustable rear trackbar? If not, you might need one to center your rear axle.
AA SYE and CV rear drive shaft (can also be ordered directly from Tom Wood's company - might be cheaper). Definitely shop around here; some places want to charge you more for just the rear CV driveshaft than for this complete combo.
You might also need to buy a pair of rear shock relocator brackets that mount on the axle after you rotate your axle for the SYE/CV driveshaft. This is what I put on mine:
