When was the Yellow light MPX stereo introduced?

[Stefano]

I still have the Blue light multi-plex stereo that I pulled out of my first 1969 Camaro back in 1979.

The round transistor on the back reads: Delco GM
DS 50
6848

The white tag on the right side reads: Service Model No 91BFM2

Serial NO 31FSC-1118
Product No 730 7331

Delco Radio Division G.M.C. Kokomo, Indiana

The part number on the buttons is 7306391

There is a number above the left control Knob 730 7746-1

Now if I could only find the Camaros Vin number?

It was a neat Camaro: Silver with Black vinyl top and Deluxe interior.

I purchased it from the original owner who bought it off the showroom floor. He told me that it was a real Z28 and that he traded a Boss Mustang in on it, once he got his doors blown off on his first encounter with a Z28.

It was a bargin at $700.00 as it only had just over 100,000 original one owner miles on it back then.
