'65 dart/ four speed driveshaft same as automatic?

Hey guys, I found a guy who has an 833 from a '64 dart with the same ball and trunion style output as my '65 gt with an automatic has. Does anyone know if the driveshaft lengths are the same, or will I have to have mine shortened?

The best part is, the guy wants $75 bucks for it, says he had the cover off it and everything looks good. But even if it needs a rebuild kit, I'll still only have $200 or so in it
