well consider this, when i went from 1/2 to 9/16 on my 8.25 i thought well 100 ibs is right for 9/16. so i tighten to that. drove around a few days & noticed my drivers side was sitting lower then the pass. side in the rear, measure it & its a 1/4 " difference. it was always dead even before the u bolt change, so i crawl under & start looking. the u bolts had crushed into the housing tube on that side by a 1/4 ". to get it level i had to loosen all 4 u bolts , put a 1/4 " shim on the drivers side perch. then i retightened all 4 to 65 lbs. been fine ever since. i have never seen anything like this before, so looks like you can go too tight at least for the housing tube that is. wierd thing is it only dented in on the one side ?

Appreciate the responses. The reason I ask is because on my 8.8 swap I torqued to 100 (they are 9/16). The tops of the u bolts that would get cut off are now not completely straight up and down after torqueing the bolts.

I have reused head bolts because i was stuck in a pinch and the motor still runs fine.Or a driveway alignment with a long enough piece of string or rope a few times.But i have always owned old junk you can get away with a lot more then a modern car.
