Whats up guys and gals! Im new to the forum and wanted to get some info from people. well i have a 84 shortbed that used to have a long stlye th400 with slip in yoke,now that took a dump on me and just picked up a th350 shorttail from jegs. what iwanted to know was how long would the drive shaft have to be to fit with the new tranny? Could the old drive shaft be used? my existing shaft looks to have been cut down to fit the th400.Now i got the truck as is so i have know idea how long it used to be.But has a small slip yoke in front which i would assume was supposed to fit either 350 and400. what length does any one have for their driveshaft for a short tail th350 with a stock rear end? and is it a one piece? Thanks in advance
