Thanks, Lonnie! Mine was rebuilt and repainted silver at some point tho so there's no original finish left. ...I bought it that way from baldeagle, my truck actually had a recirculating heater that had an original dark bluish almost black textured finish on it. Decided to go fresh air when the opportunity presented itself.
I was thinking it should be a lightly textured bronze/tan color, slightly darker than the pearl beige dash paint. Doesn't need to be 100% accurate but I'd like it close to original looking.
