Just another k.h. Swap thread.

Last I checked, disk lower ball joints (w/ steering arm) cost about half the drum ones, with the later getting hard to find (squirreled some on shelf). I recall the bolts are kind of special, but Grade 8 bolts with lock-nuts (all-metal type best) should work and Ace Hardware carries them. For those converting 10" drums, my 1965 Dart had one threaded lower hole in the 4 spindle holes which mount the drum backer plate and ball joints. I though that bolt was stuck in a thru hole with rust, so beat it out only to find I had stripped the threads. Perhaps they did that for easier factory assembly since it also had a nut at the end of the bolt.
