My solid axle swap went through two phases of construction. The first utilized Trailmaster 4" coil springs and Rancho 9000 shocks. The setup was a 5 link, that is 4 links plus a panhard bar. The coil spring was allowed to fall way from it's upper mount and was kept in line by a piece of tubular steel which also served as a bump stop. The axle is a Dana 44 High Pinion design from a '79 Bronco. The axle was shortened for this application. I do not have the measurements. All of the fabrication work was done by FST in Phoenix Here are photos from Phase 1: Main drawback to this design was the noise and sloppiness that occured when the coil spring fell away from the top mount. Everyone I wheeled with had to get used to the BANG when the coil popped back in place.
