Hi Jeff, firstly welcome.

I'm not 100% sure but I think there is very little or no difference between the two, other than fenders.(Where there's a will there's a way!)
Hopefully someone more knowledgable will chime in to confirm our suspicions!
You could also contact these guys to check....
I hope this helps.
