Do a bit of a search first and check out how hard it is....alot of people on the board have done it and would be keen to expain the ins and outs of it if you dont get enough info from other theads. Then make up your mind on taking it to someone else, as it will cost a lot more for them to do it.

HI there, shackle reversal is nothing too difficultl to do and the average joe should be able to do one without too much diffulty. A major benefit is comfort (if thats what your lookin for) This link may help

Shackle reversal is easy...as long as you understand castor, pinion tracking, diff rotation, driveshaft bind and driveshaft drop out!
Apart from obviously altering the steering geometry this modification also causes the pinion to track differently as the suspension cycles through articulation. In a short wheel base it can cause you to steer out of corners instead of into them but the worst problem is the pinion tracking where the diff will not only rotate away from the transfer (causing uni bind) but will also pull away from it causing the splined shaft to be extended beyond its capacity (hence the front shaft will fall out).
In short though a shackle reversal will work well for improving comfort, approach angle and step up ease but the problems will occur if you want any reasonable articulation from the set up.
The only real answer (and it is not a perfect one) would be to fully build a new drive shaft with hyper angle unis and an extended slip joint (read as dollars).
