I was pulling a few parts off of 79 Monte to use on malibu and to keep,sale, trade etc. I took insturment cluster off that someone had put about 4 to many screws in. Round gauges. Speedo gone. Clock still there. Kept plastic lens. Started to keep clock but it was missing stem...anyway I noticed only the fuel gauge had a needle. The other three "pods" were blacked out from behind. One was choke, one was temp, other was oil. When I took it apart it had black factory film behind it. Anyone seen anything like that before? Just thought it was odd.
