That is a 60 cross-member attached to the tranny in the last picture and the 68x60 is an early bolt pattern for the 60.
Take one last picture of the main drive gear where it mates to the tranny, that will be the definitive answer the 40 gear is different.
But this most likely was in a 60 seeing the gear shifter and the cross member, I must have just missed that in the earlier pictures.
Going back to the picture Mark you are correct. it is a 60 trans.
And the rebuild kit is only$200 shipped.
