Transmission, torque converter, updated starter questions

What about the lack of rotation of the driveline studs when I spin the TC? Also, there doesn't seem to be a positive seal against trans fluid leakage between the TC and the trans....Is that just

From the pic in post 6, the TC is in deep enough; the lugs are below, the face of the bellhouse.
The flexplate and TC have one hole offset. you will want to find and mark these now, to save you the hassle to find them later. After indexing, I rotate the crank to put the marked lug pointing straight down. After the trans is installed, you then just pull the TC forward, rotate the marked lug down, and install the first bolt finger tite. Then rotate and continue. Then torque them up.

Huge thank you AJ for bringing up the offset alignment of the flex plate....If you had not mentioned that, I would have fought and fought that battle later. Now things are lined up, spray paint my starting lug location on the flex plate and TC...Onwards! I also came to discover that there is one bolt that is coarse threaded and the other 3 are fine thread. I would have guessed that the coarse threaded bolt was the off centered lug, but it doesn't look like it from what I can see. What is the purpose of this difference?

Thanks again guys.....
