Bought a Burns but really want a USA1. USA1 are rare as hens teeth in the UK, but Burns are slightly more common.

Can anyone list the critical parts I need ?

Easy ones

Wheels and tyres
Shock plates BS-80
Four more gold shocks
Transmission, this is a big one, I see I need numerous parts for this as the gear set in the burns is quite different between clutch and front and rear diffs.

other:
body
body stands
rear hoop
stubby front bumper
