Drop Spindles - PST vs. Magnum Force vs. Fatman vs. ?

Hi
Maybe I was given the wrong ball joints but there is a greater distance from the centre of the bottom ball joint to the hole of the tie rod end.
There must be atleast 3/4 inch difference in the length maybe more. I tried to upload a photo of one I had silver and the magnum force unit black. If it uploads you will see.
Regardless of where the wheel ends up the tie rod is pushed further back from the axis of the bottom ball joint. Simply because the bottom ball joint is physically bigger in every respect including its length between the ball joint axis and the tie rod.

The lower ball joint from Magnumforce is just a regular disk brake lower ball joint. Nothing fancy or special about it, it wasn't designed to improve bump steer or anything for use with the drop spindles. The drop spindles were patterned after 73+ disk spindles, and that's the stock lower ball joint for those.

You'll have to excuse me, I realized that the early 9" drum spindles had a different bolt pattern for the lower ball joint, but I didn't realize the steering arms were also a different length. I don't have a 64-66 car, and my GT's are 10" drum cars which use the later style lower ball joint. So, I forgot that the lower ball joints change on the early 9" drum spindle cars.
