Good looking rebuild. I just picked up pretty much the same trailer as you. I am having a lockable top made, some jacks in the back for when its not hooked up, and a bumper with a 2" receiver.
My question, I have beed looking for the Dexter 55" 3500lb axle with a part # of NS35655I-ST-EZ. I can't find it. Went to etrailer and all I could find is the 60". Am I missing something (which could very well be the problem).
I think I will go that route with the axle, and yes not having the trailer brake will suck. But parts availability is a good idea.
Again, looks like great build.
Thx
