I'm not running any rear brakes or leaf springs so I was able to mount the inner dually wheel with no spacer. The outer wheels have 2" backspacing I needed a 4 1/2" spacer between them but made a 4" spacer work
I'll cross that bridge when I get there.
The tracks are pretty loose up here well actually very loose. Our best track is probably as good as your worst track :roflmao: when it bends or breaks ill swap it out.
