Putting in my new tranny and final drive the other day,father's day, and ran into a couple of issues never seen mentioned on the forum. First thing found, after a lot of cussing and discussing, when I couldn't get the tranny and final drive in as one piece and getting it jammed in place, my son noticed the bung that the PO had welded on the side of the oil pan in that little spot open between the final drive and oil pan was impeding our rear movement of the assembly so we broke the final drive loose then after we got the tranny unwedged it went up in place. We also found out, even with the steering turned all the way to one side, you have to pull FD cover and put it at a real steep angle to get over the steering crossbar then level out and to put in tranny, so I configure a holding fixture, screwed it to my regular tranny jack and put angles under the front of it with pieces of wood, slid it up, then forward, up a little more, forward a little more, leveled out then mated it to tranny, Yahtze! And the final discovery was the flex plate bolts would not go in the new torque converter, wouldn't you think that these would be SAE threads, the new one was, I think, after awhile I checked the bolts and they were 10mmX1.5 metric, I needed 3/8" 16 like the new torque converter had and what you would logically think would be in it. the pitch on the 2 are almost exactly the same but the 10mm is .015" wider. 3/8" 16 flex plate bolts are Moroso 38765. If people around LA hear laughter it's probably Jim K. he's been working with me on this project long distance for over 6 weeks and it has been a comedy of errors, I'm glad we both have a sense of humor to get us through it. Just a few things that might help someone later. I'm putting those bolts in tonight, hope I'm right about that, if not the bolt holes are way off in the torque converter.
