That is an extremely short driveshaft input shaft.

1. Remove your driveshaft
2. Look at where the splines start
3. Cut some of the shaft down close to wheee the splines are, remove sharp edges.
4. Insert shaft into trans, pull shaft out about 1”
5. Measure for driveshaft length

For comparison, here’s how much yolk is showing on my 68

Is that the factory drive shaft?

Yes.

I would start with that driveshaft for sure. It appears its to short and not correctly installed in that tailshaft. A T5 and most transmission swaps typically involve getting a custom driveshaft in the correct length.

Having one made is easy. You measure distance from transmission to flange on the diff and talk to a drive line shop. They make what you need, Or even easier take what you have that needs to be modified and they retube it to the correct length.

When I did my T5 swap in my 70 XR-7 I had the original drive shsft cut down I think it was 5/8 inch and rebalanced Look for a local shop that does this kind of work.

Sone bigger diesel truck shops do driveshafts

Just curious - did you verify the bell housing runout? The T5’s are very sensitive to that being correct.

GOOD NEWS!

Today me and my brother swapped out the Aftermarket Aluminum Drive Shaft for the Factory Drive Shaft with a shortened Yoke. It fits WAYYYYYY better ! I took it on a test drive and i have little no no vibration at all. I think if i remove the 2 degree shims that i installed it will ride perfect! I drove my car around the block a few times today for the first time in a while and im super stoked ! The Aluminum drive shaft that was installed is from a foxbody mustang i believe? I bought it with the lot of parts for the t5 swap from a guy on Craigslist who swore that everything would work with the parts included but they didn’t. Anyways, thought i would share this story with everyone. On to the next project, Export Brace and Subframe Connectors!
