I measured the T-4 in my Garage yesterday it is 24" from Bellhousing face to tip of tailhousing where the output seal is pressed in. Same as others I have seen measurements on. I've been thinking of this T-4 and possible uses for it. Best one I've com up with so far would be for a drag/ road racer wanting to build a light weight 4 speed. Stuff a top of the line gearset on a world class main shaft mount it in a Ford World class T-5 main case then add the T-4 Tailhousing and top cover shift assembly. Your shifter would still fit the factory console in Concords, gremlins Etc; And you'd have a stout 75 lb four speed! I think some of the gears sets are rated at 500 plus horsepower and ft lbs torque for T-5s. Some of the race T-5s are sold without fifth gear in place anyway. You might have to mill off the end of the cluster though. I'm not sure how that would work.
