At the risk of exposing a good ebay find, here is the transmission in question.
Item # 180414797099
The seller says that it has a 10 spline front and a 16 spline rear shaft. I was thinking about hooking this to a blown 292 in the club sedan 
. I also have a good 56 wagon rear end that I would like to use (obviuously taller gears for good low end torque) for this setup. What do the numbers T86E-1N stand for?
