I just got a 2" shackle lift for my 55. I was looking on specter or jt outfitters or somewhere for the bushings so that I can install it sometime in the next little while. They have 3 different sizes listed. I was wondering if theres a way I can find out what size bushings I need without taking off the old shackle and measuring one of the old bushings. Its a 1973 if that helps with figuring out the size. Thanks
