73 Charger with odd options???

[knkmoparparts]

Hello everyone, I just got a very rough project/parts car. I had a couple of questions about some of the options on this one. It is a 73 Charger Coupe ( WL21G3AXXXXXX ). This car came with a M52 Manual Sunroof, and is JA5 (Dark Silver Metallic). The first question is the F92 code which is a Thermo Ignition Vacuum Valve. What is that??? The next is a Y33 code which is Fleet Sales. And a Y97 which could be a Show Car Finish or 3 Gallons of gas. Which I think it is probablly the 3 gallons of gas since it was a fleet vehicle. Anybody out there have anything similar to this???. Would love to hear from anyone.......Thanks Kevin

I can't help with those other codes, but a WL Charger with a sunroof is very, very unusual.

weird somebody buys a sunroof car with fixed quarters windows instead roll down.

But everything is possible.

 I believe the thermo ignition vacuum valve  sits between the carburetor and the distributor.
Until the car is fully warmed up , it will not let full vacuum pressure get to the distributor vacuum advance module.
