That's your typical short shaft trans made for HD applications with a 2 piece driveshaft. Personally I wouldn't use a 2 piece shaft in a car. Not even sure the trans mount would be in the right location to bolt up to the crossmember. If it were me I'd round up an output shaft and extension housing for a car and swap it out. You also never know what kind of shape that trans is internally unless you pull it apart. Remember, it's a 39 yr old transmission. Could be 90% worn out. It is a heavy duty unit good for building a super tough trans with. I started rebuilding torqueflites when I was in high school shop in 1981. If a 17 yr old kid with very little automotive experience could rebuild them most anyone with decent mechanical ability can.
BTW: here's a link to a good place to get good used trans parts cheap
