I was installing new differential carrier and tranny crossmember bushings, the ones from SCP. I ran into 2 issues. I have a '90 SC. The crossmember bushings were rectangle and now are round. I read in a forum that I need a cap washer and different bolts for these new bushings. Can I buy new or can I use used? I could probably find used on here. Issue 2 is with the diff bushings. The manual shows torque to 65 - 100. That is the same way it shows torque for bolts on the motor as torque to 1st number then come back and torque to second number. So I took it as I should do the same here. After getting to 65, I thought why do they need to be any tighter. The nut is already on further than with the old ones. But I tried anyway. The bolt snapped before getting to 80! How tight do they need to be and where do I find new bolts? They like the type of bolts that aren't supposed to be reused because of stretching. Any info would be appreciated.
