The rockwell is a tough tcase. The one I had in my 69 came out of 67. It hadnt been touched since it left the factory and after 44 years it just now finally wore out the splines in the collar that conects the tranny to the tcase. The thing was pretty tough, I have no complaints about it. I took the covers off and all the gears inside look to be in great shape. Like I said, nothing had been done to this thing since it left the factory and it shifted into gear and ran flawlessy. I think the t221 is a pretty good tcase.
