on the topic of ubolts and plates, it's possible there's something up where you'll be fine if you keep them together but just can't mix 35 bolts with 44 plates and vise versa. I'm not at home to verify, but I remember having trouble when I picked up my trailer. I had to supply the leafs and we assembled it on the spot and I remember having trouble getting the bolts to go through the plate. He dug around for the other set of bolts and everything worked ok. Problem is that I don't remember the specifics.
anyone have a set of both lying around to compare?
