I think I'm going to need one of these, too. Got my late model set up this weekend and I don't think I'm getting enough speed with 32/69 gearing. I think I remember Steve saying he had to go all the way down to a 60.

I'm running a 35/69....still haven't conquered it 100% but close.....I bought a 60t from Butch Fri. and put it in ...way to much power for me....would'nt even know it was the same car...thanks guys for the info I see what I can come up with....I googled robinson and couldn't find anything...moose has a 66t so someone has made them a.t one time or other.

Tom, just click that link I posted. Tower sells all kinds of Robinson spurs and pinions.
