Pre-66 humps will fit, but they have a round hole. 66 hump is a one-year-only deal. I have a 66 hump I can dig out and get pics of later today. If you need comparison shots, I have an 78 A833OD with shifter and rods, a 65 A833 4-speed that "I think" has shifter and rods somewhere, and a 72 A230 3-speed no shifter or rods, all sitting loose in the shop if you want photos of them.
