Welcome to the community J. Your 80's previous life was rough. You should be good to go for many more miles now.
Here's more of a break down of what was causing it to pull right.
The bearings, TRE's and knuckles were worn for a typical 265k mile 80 but wasn't causing the issue in question...
I just cought up with Mud.
I have looked at that 80 for other folks. It has been beaten hard. I'm going to recommend replacing those control arms with Delta or at least stock. Way too many hard trips on this rig.
Send me a pm if you would like to come by the shop the first of next week.
Casey...
