i came across a guy with a complete drivetrain out of a 73 K5 for sale real cheap. he has a Dana 44 front, a 12 bolt rear. both have 4.10 gears, and the rear has a posi. he's not real sure which trans and case he has though. the trans is a 3 speed manual, and the case is a part time unit. i assume the case is a 205, but what about the trans? assuming it is a 205, what other trans could i bolt to this case if the 3 speed isnt worth a crap?
