Locked up Slant 6

Remember, if you put a '68-up engine in front of a '67-down transmission, you need to install a spacer ring to take up the space between the large ('68+) crankshaft rear counterbore and the small (-67) torque converter nose. The ring isn't difficult or expensive to get; look for user Charrlie_S on here or on slantsix.org .
