Dont have a part # but i used a 2" block in the rear and cut 1/2 a coil in the front. If you dont want to cut the front then id use a 2.5-3" block in the rear to keep it from looking like its sagging.
I cut down a factory block in the back of my truck without issues.
How did you do it and what did you use?
Pics would be nice.
I used a band saw and a drill. Don't have any pics of the blocks before/after.
It would be nice to see some pics.. ya'll think 305's would still fit upfront with stock height?
