I have a heater box a guy is interested in. I thought was a 67-69 heater. But on checking it out it has only 3 studs that stick through the firewall ( in a triangle pattern )on the blower motor. What year did this change ?
Heres pics of 3 I have, all from 67-9 cudas. 100% sure. Model 702 is the one with blower all attached. I believe all 3 are NON ac, that I'm 99% sure. Only 1 I see has blower motor. I can pull them out for better pics if need be Al?
