how do the AZL 100t and FT 70t wheelbases compare? The AZL looks (correctly) slightly bigger.
I'm thinking an AZL 36" wheel in a FT truck will be a great stand in for a 100t truck.
The Full Throttle wheelbase is 66 inches; 68 is correct for 70-ton roller bearing. The AZL wheelbase is 70 inches, which is correct for a 100-ton. (For reference, the M-T wheelbase is 60" which is about right for a pre-1900s archbar.) Unfortunately, AZL wheels will not fit in the FT truck.
