How short of a driveshaft is too short?

Hi all!

I'm new here , but have been reading up a lot and researching. I'm building a T-Bucket from a kit. Right now I'm mocking up the motor and trans in the frame. I seems that the tailshaft is too close to the yoke on the rear end. I would think there should be at least a 18" from the pinnion yoke to the tailshaft. The way is sits with the motor and tranny mounts that came with the kit, theres only about 12". By the time I put in the slip yoke on the tranny and the solid end of the drive shaft, the tube would only be about 6" long! The mounts were desinged for a small block chevy, but of course I want to go against the grain and use a Ford combo. Any ideas if there is some minimum distance?

Thanks

I am glad to finally hear someone is daring enough to put a Ford engine in a Ford T-bucket.

I would have to recommend discussing this via e-mail or phone with a prominant driveshaft shop.

Check in my Axle Information sticky post at the top of this forum and see if I put the information in there for a link to Inland Empire Driveshaft, and Denny's Driveshaft, both of them should be able to tell you what can be done and recommendations if it cannot.

From what you have described my thoughts on this would be towards this combination:
Transmission slip-yoke, constant velocity universal joint, and universal joint flange.

This combo will allow more movement with the CV joint, the slip yoke on the transmission tailshaft will allow what little length change you may need, and the yoke will hold the universal joint that will also mate with the pinion flange.

I like it

Thats a great idea, I like how you think. No custom driveshaft, no welding, balancing, waiting for a machine shop. Those are all pieces I could put together off the shelf and save $100. I'll see how it fits.

Thanks again
