On the original truck housings for 6-226 there are threaded holes in the two bosses that stick out on the left side of transmission to bolt clutch plate with the ball for clutch operation,do these reproductions have those threaded holes like the original?

Willys Jeep Parts Tech:
For the Truck/SW those will not be there on the case.

This reproduction case doesn't have the mounts for the oil collector. Is the oil collector a necessary item for keeping the oil where it should be.?

What alot of people do is go without them.
