TDA-stamped rear end to posi conversion?
I've got a 6-lug 3.73 open rear end in my '70 that I'd like to convert to posi. It's stamped with 'TDA 1001 W', which tells me it's 3.73 open, manufactured in Warren, MI on 10/01.
If I've decoded things right, this should be a 8.5", 12 bolt, 30 spline, type 3 housing rear end? Can I just swap the open guts with posi guts, like an AuburnGear unit or thisYukon Dura Grip, and I shouldn't need to do anything to the housing or axle tubes, correct?
