You might want to use a TJ kit, and try to buy the perches from Clayton, ot us a TJ kit and use the perches from your stock axle, or someone's broken dana 30...
I used my stock from coil perches on my new rear axle...
Also, why not go long arm in the rear? It's SOOOO worth it, both in terms of function, and ease of axle swap. Honestly, that's about half the reason I'm longarmed.
I'm with 'zombie' on this one...I did my 8.8 and LA at the same time sooooo worth it!! Can't wait to get my front done! Also...there are countless threads on MC that have all the brackets and part numbers list ed from ballistic fab....there are also some I posted on another thread on RME
