Trans mate-up

On the Slant-6 the first year for the large torque converter nose and crankshaft counterbore was 1968, not 1966 or '67. You can use a '68-up Slant-6 engine in front of a '67-down automatic transmission without dooming the trans front pump bushing and seal, by means of the spacer ring previously mentioned. You can buy it from Pat "Torqueflite Patty" Blais.
