I recently installed a pro comp 8" lift on my truck that i swapped from a guy wanting all my stock stuff. I would like to take out the back blocks so that the truck will sit level but to do so i need to get shorter U-bolts because as it is i can barely impact them down before bottoming out in the impact socket. Plus the threads need to go a lot shorter on the U bolt. I would like to just buy new U bolts instead of trying to shorten and re-thread the ones i have....Anybody have any ideas where i can go to get what im looking for? or how to determine which U-bolts i need exactly?
