I brought these home yesterday. I was told they came off a 350 Buick engine out of a 1970 Jeep Wagoneer. I found that the number 300596 on the Dana 20 tag indicates that it is a Jeep transfer case. Don't know what the other numbers are, maybe part number? The transmission and transfer case both turn freely and the transfer case shifts into all positions, 2H, 4H, N, 4L. Didn't get a flex plate or torque converter.
