Gear change selector question

[Lynn Eades]

The carriers are built using BSF threads, but the Ford built stuff is still UNF,UNC.
Your gearbox top is post war withe the sprung loaded internal reverse detent.
You can mahe up a plate to bolt on the lid (left side) to support the short end of the gimble. The australian carriers have just that. It bolts on with longer lid bolts, as their gearboxes never had the appropriate cast lugs on the left side.
I can check the gear lever thread, and height from the ball to where the bottom of the gimble sits , if you want.
