Just took a couple measurements. Looks like a modern u-joint will fit in the spherical end of '30s-40s Ford torque tubes pretty easy. Just have to make sure it doesn't travel back or forth enough to smack anything. Also thinking a "soft" mount for the flange/bracket mount might be a good idea. Basically what ford did.
It will only go so far forward so I space it from the back so there is about 1/8" room to float. I put soft (urathane) mounts under the transmission rear..
Now I'm pondering the sealing of the rearend, or rearend and drive shaft. Could do something like the homemade open drive conversions (like Tman's) where ID of the torque tube is adapted to hold a seal and the seal goes against the driveshaft, or coupler. The top end might be easier tho, up by the bronze bushing. Hmmm
Stock '35 or later rear end? Just the outer most one that carries the pinion? That would be way tooooo easy.
It's a QC... so the jackshaft bearings. There are a few places out there offering seal plates for banjo rears. Or you could make one pretty easily.
Found a Seal Plate on "feebay" but I don't think this is what you guys are talking about. Sure is cute tho.
This looks more like it. Next is to compare bolt patterns to Ford. Looks easy enough to make to adjust and mess with seals to find one that fits the bill.
Haha! Yep, I actually have to make one for my coupe, mine's got an open bearing in the front and every few hundred miles I have to drain a cup of oil out of the trans and pour it back in the rear end!
Hey @Flat Ernie, what happened to The Ultimate T - 5 Swap Article? It was here, but now the link is brokeb: http://www.flatheadv8.org/ernie/ernie-t5.htm It was epic. I hope it can be restored.
I don't know...it's here on the HAMB too... First article in this Tech Archive post found in my signature: http://www.jalopyjournal.com/forum/threads/transmission-t5-tech-links.169265/
