xxx-nt gear ratio

[Racerjmh]

Anybody know the gear ratio for the xxx-nt transmission? I am trying to match gearing FDR with some friends gt2 and gt for oval racing. And is there any other spur gears out there for this truck?

Found it out myself- 4.11 to 1

I thought it was a 2.60 diff ratio? I could be wrong though.
