He literally said he was running the same wheels and tires on the 73+ spindles previously without any issues and just changed them side for side because of the changes he made with the brakes and sway bar.
I had to read that a few times. And just read again.
I'm not super clear if there were changes made without tested road time in between them. But it sounded like he ran 11.75 rotor w/calipers mounted in rear with 235/60/15 tires for 10 years.
These deals can be tough to follow.
The odd thing is, you should/can be able to swap spindle side to side without disturbing the UCA alignment cams and not remove the strut rods.
