Hey guys.....I remember a step by step ( with photos) of how to replace the 4 leavers for the delux heater from 63 to 66 CMC suburbans. I have the kit now and knobs, but can find the post on HOW TO!
Just be carefull with the small piece of glass that the light shines through, as I found out when I broke mine and had to get another from the junk yard.
