Don't quote me on this, but I think the shackles are the same. If you swap the rear leaf springs, you'll probably have to take out the factory installed 2 degree shims to get the pinion angle back into spec. But don't take our word for it, it's best to measure before and after anyway.

 

What do i use to measure the pinion angle and what is the best way? Thanks.

 

There are several cheap and expensive measuring devices, ranging from simple mechanical protractors to digital/optical jobbers. I used a parallelogram protractor myself. There are some good online resources with lots more info, search Google. One such link I found was:

my 94 f150 2wheel drive short bed. i tried lowering shackles did not work, still let the rear did not drop. got a set of perch seat flip leafs droped to low went from a 34" to 18.5".. took degree measure b4 i did all this. 5* on the perch seat ontop of axle and a 10* on the drive line. had an idea for something different took a piece of 4" c channel clamp it to the frame at the rear hangers. drop the spring hangers to the lowest bolt holes drilled out the holes for the c channel bolt it all up and set the pinion to what it was to begin with. should this be the same as lowering or do i have to reset the angle. obw. front is 31" and rear 31" level as can be.
