I've been browsing around this site for a while looking at trailer builds and just now joined. I picked up a M100 in relatively good condition - I'm at work right now but I'll post a few pics later tonight. I plan on pulling the trailer from AZ to NJ and I definitely want to make sure it gets there ok. First thing is to buy a new axle. What size axle are you guys running? I want to run 35's with a 15x8 - 4inch backspace wheels. ABC trailer has a 62 inch wheel hub face to wheel hub face, and 48 inch spring mounts, wheel this work? I want to keep the springs and just replace the shocks. I don't care about the brakes, I'll just get an axle with the brake flange so I can add them later. Is it pretty much a requirement to change the spring bushings when you do a SOA? Thanks for your help.
