Hey Russell! I spoke to a man yesterday at a Houston based driveshaft shop. Of course which is always on the other side of town! I told him the measurments of the rear yoke, he said, that's a 1310, (of course, I knew that!), then the way he told me to measure was from the output shaft itself on the tranny to the flat surface of the yoke, you know like where the little brackets that hold the caps in place. Kind of makes sense. I came up with 55.25". I'm taking the driveshaft to him this morning and he'll have it back to me tomorrow, about 125.oo for the service of which I thought sounded very fair! I worry too much! I thought getting a driveshaft was going to be like my windshield!
