1967 904 Transmission

The crankshaft register diameter got bigger in 1968. You will need one of two torque converters. The determining factor will be whether your engine is internally balanced or externally balanced. If the engine is internally balanced order a converter for a '72 318/904. If the engine is externally balanced order a converter for a '72 360/904. You will also need the corresponding drive plate for each converter. Your 273 converter and drive plate won't work.
