Rooster Comb Swap

yes, you can swap the 72 comb onto the 67 VB. End goal is a good VB?

Exactly; thanks! And just to ask what may be an obvious question: After I put the 72 comb onto the 67 VB, can I put the modified VB into the 67 trans, install a 3-post switch, and have neutral safety and back-up lights at the trans?
