The new front axle I needed came bundled with a spare 1974 rear axle. This is a 4.10 with a disc brake conversion kit and calipers on it. I've not run it personally but claimed to be good from the person I bought it from.
Located in Orange County.
Asking $600 which seems reasonable but talk to...
@3_puppies - thanks for pointing that out, I’m assuming the front was opened up and possibly messed with as well, I will try to figure out what’s in the front tomorrow.
Thanks!
