Help!! i got to figure this out

I'm planning on ordering everything for air ride tomorrow, i need to figure out what to do with the rear. I really want to keep the stock gas tank location but raise it up a little. I"m going to have only a front back setup, i was going to go mono but i was reading about this toyota that kept blowing out tranny seals because his driveshaft was getting pushed into the tranny with a mono leaf setup. so now i don't know. I was also thinking about doing a parallel 4 link, and trying to squeeze it on the outside of the frame rails cause i have 2" of clearance between the wheel and the frame, but that's probably not enough. reverse four links i hear are a no no. I"ve allready ordered a watts link from byc, and i want to use it. Any sugestions are welcome please, thanx-mike
