Replacing Stock Leaf Bushings with Poly

Hey,
I am installing a set of leaf springs on my 74 swb. I replaced the leaf spring eye bushings and the shackle bushings with polyurethane ones. I had to cut the outer shell out and insert those 2 piece bushings in their place with a new sleeve. My question is how tight do I need to torque the bolts down with the poly bushings?? The original specs called for 75-105 lbs. When I torque these bushings down to that it gets real tight. I feel like the poly probably calls for something less. Does anyone have any idea??

Thanks for any help.

Check with the manufacturer. Lots of guys have done that here so somebody may have good figures if you can't get them.

Hmm, I've always torqued poly to stock specs. Never had a problem.
