So, it's looking like someone cut the countershaft to fit this transmission with the longer tailshaft. Number on the tailshaft is 2602526.

The transmission has a sliding yoke, as does the countershaft. Seems redundant and this is probably why the carrier bearing walked out of the rubber bushing towards the transmission.

I need help with the following:
1. What transmission is this?
2. Should I get a proper countershaft, or a single piece driveshaft?

Mine has the 3 piece shaft, and has been converted to a slipyoke type transmission.

I've had no issues with my setup, was the splined slipyoke by the center support bearing stuck?

It is most likely from a car. It should have a tag on it somewhere post that info if it is still there.
The simplest solution is to have a one piece drive shaft made using a slip yoke in the transmission. If you are near Johnson City call Bowman Driveshaft, 423-282-8009

I'm in Knoxville, there's a drive shaft shop here.

I found 2 numbers on the transmission (attached). I suppose the follow-up question is that is this transmission worth making a driveshaft for?

I don't have a parts manual and my interchange book only goes to 1975. But just from the looks of it it's a type 3:03 with a 77 part number. It is probably worth getting a driveshaft made for if it's working OK. Most of the differences in the transmissions had to do with the tail shaft housing and output shaft. The only problem with a one piece shaft is if it gets over 5 ft.or so long you may have to go to a 3 1/2 inch tube.
