there weren't any markings or numbers on it. ( thanks toyota )
the guy at toyota looked it up on the computer for a 85 solid front axle and it looked correct, the problem was that it uses washers that range in size from like 1.1mm to 1.9mm and at like 15.00 each I didn't want to buy a dozen or so to find out.
It is 30 spline cause the chromo birfields fit but you can turn them way to easy, however in light of spider gear preload I didn't want it too tight.
I will get some pics posted as well as some measurements
