67 none ac heater controls in a 70 model will they interchange

Sorry but 67 is totally different. Mounting bolt on the left side was placed between the fan switch and sliders. 68 and later have both bolts at ends. The 67 levers pivot rather than squarely side so the slots in the 67 bezel are longer also.
Someone should reproduce those little plastic guides for the 68-72 controller but I've never found them. good luck
