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

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.

What else is starting to piss me off.
I was starting to think because the Aussie car's are right hand drive. I thought it may have been a difference between the cars from the west Pacific to the east. I do own a 1964/5 a Barracuda left hand drive and I checked it, and it is the same as my Aussie car.
To stop any drama I actually ordered the stuff ias if they were for the fish in the first place.
I have been considering to put a rack and pinion in the steering boxes place. Just need to get one with the same spread between the inner tie rod ends I think on my Val it's right on 2 foot.
Using the holes in the frame rail for the box and the pitman arm joint as the rack mounts.
Some bump steer can be removed by having some adjustment of the rack in the vertical direction.
You lefty drivers the box is on the k frame.
In fact my Val has the mount on the K frame and even because whilst the new Chrysler factory was still being built in Australia sub assemblies of cars were shipped from the US.
If you look at my gallery you will see a pick of the two master cylinders below in the dark you can just make out the in shaft of the steering box.
As Aussis Vals go mine is also an odd one because it's wipers are for left hand drive most others swing the other way.
