Cool build! And in my own backyard.
Trying to think of any spare parts I have that could be useful, but coming up pretty blank. I do have a pair of UCA’s with decent ball joints but one is cross threaded and is probably junk after the balljoint wears out. Should be useable, until then, though.
Couple of thoughts;
I would check any BBP axles to see what bearing they use. Many use “Green” ball bearings instead of the factory roller bearings. Some pluses and minuses to both, but I would avoid them for a cornering rig. No idea if they have any durability issues for normal (daily) driving. And I think most rear disk brake kits use them as well. Might be that they are ok, just something for you to be aware of.
You don’t need need lower control arms to replace the LBJ. The LBJ bolts onto the spindle and the stud goes into the LCA. I would look at new TB pivot bushings and bracing plates and just use what you have. Unless you want to spend the money for aftermarket LCA. Might add sway bar brackets if you don’t have them.
Can’t think of anything else, but I am local if you want to look at another 4 speed Duster to compare or something.
