I have a chance to get one of these RUG CL '78 model transmission for free, but i got quite a drive to get it. My question is is this thing worth goin to get? Will it even fit? Only considering it because my CR toploader has major problems and i need somethin pretty bad. I doubt this thing is worth gettin, but figured id ask cause i dont know much about transmissions other than takin em out and puttin em in and installing shifters. Thanks in advance.
