Disk brake conversion, ball joint hitting lca

When I added BBP disks from a 73+ a body to my 65 Barracuda back in the day as soon as I went for a road test, I remembered the article I read a few years earlier you need to trim the turn stop nub on the lower control arm ball joint 3/8 or it won't turn very well, so I measured the old parts and confirmed trimming about 3/8 was needed, worked fine after that.
