Thanks man, one more question while i'm thinking about it...
What generation rears did you use? Is the main leaf from a 1st gen?
Reason i'm asking is a 1st gen spring is 48" long and 21.125" from center pin to front of spring, where a 2nd gen rear is 48" also but 20.5" from center pin to front of spring, thats 5/8" further forward without touching the shackle angle/mount because they are the same length end to end. A marlin/tg/allpro front spring is 47" long and 22" from center pin to front of spring. So essentially if i were to build my rears using the main leaf from my rear 88 pack I could move my front hanger 1" forward of where it is recommended for a normal lift from any of the above companies and it would allow me to use the original shackle mount and still push me 2.5" further forward than any of their springs, which they all claim to push the axle forward 1.5". I think that makes sense.
How this pertains to you... you said you wish you would have moved your crossmember another inch or so forward, well if you are using the original rear springs from that truck as your basis for your ruf, then you could look for a 2nd gen rear pack and get another 5/8" forward without moving the shackle or crossmember at all, just some food for thought. I know 5/8" isnt a ton, but if you are barely rubbing as it sits now it might be just enough to clear everything. Take into consideration though that going forward even more will affect your caster more and may cause issues with clearance between the tie rod and drag link, but i'm sure you already know that.
