Bob - thanks for the chart. My setup appears to be right on at 31"/34 1/2"/36". I would have thought that the spring would be longer with weight on it, but it didn't change much. The rear one certainly does.

My invoice from SoCal only indicates that it is a 47" CE axle; no identification specified for the spring. It is reverse eye with a pretty substantial arch, and they had it chromed. The front crossmember is "angled at 7 degrees for correct caster" according to their catalog. The perches appeared to be aligned correctly and not binding - I loosened them and retightened after installing the spring just to make sure. The old shackles, once removed by driving them out with a piece of wood, could not easily be put back into either the perches or the spring eyes. The pins did appear to have been coated with anti-seize. The new bushings from Drake slipped right into place, and the shackles then slipped right into the bushings with no problem. I just can't figure out how the old shackle pins could have gotten frozen in the bushings and started turning where pressed into the front side of the shackle links - twisting in the urethane bushings should have happened first. There was very little movement, but as the shackles wore out more I guess that would have improved - until they failed.

Has anyone else had problems with SoCal, in particular the Oregon shop? I could write a book about all of the issues I've had. Clutch linkage that wouldn't work; brake lines with incorrect fittings that couldn't be made to stop leaking; no clearance over the rearend; driveshaft hitting the crossmember; tie rod too long to allow proper toe-in adjustment; rear shock mounts that don't line up; frame too narrow to fit a stock deuce tank; body mounted too far back and off to one side in the front; providing hub caps that would not fit on the wheels they provided; prices much higher than listed retail; and generally sloppy work. I went with a "pro" shop to save time and get quality work, but now wish I had just done it all myself.
