Right/Left hand replacement studs?

Yes, a 65 Dart w/ 273 (2 bbl, 10" drum brakes), plus 2 other 60's Mopars. Currently LH threads, but would probably change to RH when I replace the drums or add disks someday. Sorry about your Dart. It was probably rust-free in Fresno. I am waiting for a son to call saying "your dumb car broke, so I left it on the interstate 500 miles from you". So far they have acted responsibly, but that attitude is there and they sure don't value what I loan them. Your friend's paint shop seems to have that attitude, but Small Claims Court could set them straight, or just don't pay them until they man up.
