Ball & trunion to U joint conv. driveshaft ?

This nearly new driveshaft was specially made for a 73 Dart Swinger with a truck transmission installed behind a 360. The guy could have probably just bought a car transmission for the cost of having this made but that was his choice. Anyway, I thought someone maybe could use this driveshaft for a ball and trunion to u joint conversion. It has the small u joints (3 1/4"). I hate to junk it but I'd like to get it out of here. $50 +
