4-speed driveshaft

[Dr.Jass]

I need a driveshaft for a 108" wheelbase car with a 3-/4-speed manual transmission and 8¼" or 8¾" rear axle. It needs to be from a short-tail trans, though, so possible donors include:

• >1970-76 Duster, Scamp, Demon
  
  > 1965-69 Barracuda/Valiant
  
  > 1976-80 Aspen/Volare

I can't use one from a Dart, since it uses a 111" wheelbase. '70-up 'Cudas have the right wheelbase, but the transmission's too long. I'd vastly prefer a 7290 driveshaft, obviously, but beggars can't be choosers so I'd take the smaller-joint version.

PM me with details if you've got such a piece.
