I feel your pain. You know I'm not a stick guy (904 afficionado) but if it's not an angle prob I'd bet my next to last buck on the trans but I'd put it up on stands & have some run it up & you see if you can spot anything not kosher

I think I'd put it up on 4 stands w a large shop hyd floor jack under the 3rd member just touching it for safety & have someone work the throttle & you underneath on the side. I'd think w that amt of vibration that something might be (hopefully) apparent

So i took the trans out to fix 2ndgear. 2nd gear sync was cracked in half. I put all new syncros in, and both main shaft bearings. I also replaced the rear tailshaft bushing which was thought to maybe be the problem causing the vibration. It was still good. I put it all together and actually found a driveshaft about 1 1/4 shorter. Took it for a ride and no vibration! Must of been that driveshaft bottomed on the yoke!! Everything is good now,except ! I have a slight woodpecker sounding noise coming from the trans It shifts great and does everything perfect besides the noise. I ran straight atf,im thinking of putting gear oil in it to see if it quiets down It goes away if the push the clutch in.

I think I said that back in January ....Glad you squared away your issues with that 4 spd,....now if you want to keep it together, GET THAT ATF OUT OF THAT CASE!,...use a GL5 90 weight oil only, that ATF will only shorten the life of that 4spd,...real quick
