That one straight across cut gear you see is the sliding clutch for 1st and 2nd. I'm not sure but I think they're called straight cut because the teeth go straight across without a curve in the cut, not sure actually. Anyway, I put it back together today, installed used, (but servicable) synchros, new are NLA. I decided to make some paper gaskets, even though it doesn't call for them for the front and rear ends of the case. Put in new seals and caged front and rear bearings as well. With a tube of Permatex No. 2 and two quarts of 20W/40 (that's all it holds). I'm in, and out of it, for $44.67, not too bad. It shifts better on the bench, we'll see how it does when I get it attached to the motor in a month or so. 488 on the top of the case is the serial no. of the trannie. My body serial number is 438, but its the "matching number " factory trannie to the car. They made spare trannies, obviously.
