One thing I would suggest is trying to find a local place that build trailers and sells parts. I went to Kro-Built here in Reno. They saved me a lot of trial and error.Thanks for the help. Brakes are a good idea.
3500lb might be on the high side for trailer weight.
I was looking at http://abctrailerparts.com/ for the parts needed.
I'm going to go with the 3500lb axle with new springs.
i'll post pictures when i get started.
Lots of people on here have done a spring over axle (SOA)... However I would suggest purchasing a new axle with brakes. Anything over 3000lbs requires brakes legally in a lot of states, and it's really worth it if you ask me. The additional stopping distance with just 3500lbs pushing you will surprise you, especially in an emergency situation.
