64 slant 6 4 spd to v8 and 9 to 10" drum questions.

64-66 is the same, 67 has the 1 year steering linkage. Sell that! I believe the roller pilot bearing is still available for the unmachined cranks. Im not sure if the 67 K is unique to the 68 and on but its worth putting up for sale as the steering box mounts can crack if your tie rod ends are junk. You may be able to get away with that 67 manifold in a 64, but youll have to get a head pipe made to fit the 100 degree bend that the 64 LA manifold does not have.
