is this a fair deal

No problem, there was a member up here that had ball and trunnion 4spd and it was difficult to find pieces.
Im not sure with your other questions, I'll cconcede to more knowledgeable than me.
Thanks 4spd, I'll look for the '66 and later version. Was there a year to look for that was the lightest version than the others? Did any of them have aluminum cases?
