My '66 Dart has had a transmission transplant. The 904/273 was ripped out and a 727/360 went in. The 727 is roughly 5" longer which means I need a shorter shaft.
Oh my !! I worked at Napa (counterman) and 7 years ago you could get a complete drive shaft made for half that almost (here in Arkansas) I need to price one for my 360/904 , prices have gone up I guess by a bunch.. good luck sir.
