Rooster Comb and park switch

I had to change linkage from a 73 vb to a 68 vb when installing the 68vb into the 73 case. The problem I had was that the arm on the linkage. It had nowhere to stop. So I changed the governor plate from the 73 to the 68 vb. I had to grind on two of the bolt holes so the plate would line up with all 5 holes. Hope this helps. Kim
