If you look at page 54 of the Heidt's catalog, it states that they do use a mustang II spindle on the super ride II. I'm not sure what spindles I have, but they are marked E-lan with a PN of L 1192. My searches have not resulted in any info.

If you read about how a mustang II suspension is supposed to work, on page 74, I can only hope that the cross member is made to function properly, so a line through the center of the two pivots goes through the center of the pivot on the rack.

I got a 1-59/64" ball joint socket and it worked great to remove my ball joint. Ant-seize was used, but I still saw some evidence of some galling on a couple of threads, so I asked Ride Tech to chase the threads, if they have the proper tap (a $200 item). It's likely that the threads distort from welding, unless the threads are chased or tapped after the welding is complete.

Whatever Oze used to install the ball joint sure buggered up the top of the ball joints. You're not supposed to use an impact wrench with a ball joint socket, but to remove a joint that I plan to toss, it decided to try it and it worked fine. I'll screw them in with a 1/2" ratchet and switch to my torque wrench, to get the proper 100 ft-lbs.

Unless Ride Tech recommends otherwise, I plan to use the upper arm sitting horizontal as a guide to the intended ride height. The lower arm still angles down at the ball joint by about 2 degrees, with the upper arm horizontal.
