Apparently I got a bit cranky this week because a few here and somewhere else got a bit mad at me with good reason. I guess the IRS and their incredibly complex forms that I can barely read anymore got to me... Sorry if I hurt anyone's feelings in my harsh comments. I should know better.
Rick, I will take detailed pics of the car Monday and post them. The crown gear is a Cox (the Riggen did not even exist when the car raced, and they all crack anyway). I believe that the car has flanged ball bearings at the back. The arm has the thick Manuchi laminations because nothing else existed then, the thinner ones a couple of months away. The original motor was purple because Steube was using AMT cans. For the rest, you will have to wait a couple of days, sorry!
