bear with me here. i have a 413 to put in a truck, but i haven't installed it yet. the transmission is a t-18 from a 65 jeep. the input shaft is larger than a a833. i haven't found a bearing that would fit the combo. i have 2 options: first, i could use a copper pipe coupler because it fits the shaft, but it is too big for the crank hole. I could sand it down a bit, but it'll be very thin. my other option is to use a standard bearing and hone down the input shaft. what would you do? the first option would be easier. would a thin bearing do the job??? its a very close fit without the bearing.like 1/8 inch total... so 1/16 on either side of the shaft.
