Default 73
Hmmm
Ok

My 73 455 doesn’t even have a hole in intake for one of those …

Sorry for the confusion

Scott

I think it is on some of the 73s and 74s.. And of course mine has it, and I can’t find it. Or anything that would work.

Default 2-Port Thermo Vacuum Switch
BFMGTO,

I have a 2-port Thermo Vacuum Switch I removed from a 1973 Grand Prix years ago. Looks just like your photo. The steel hex has some surface rust and one flat is pitted. If interested, send me a PM or email at [email protected]. I can glass-bead blast and send photos.

Thanks, rockys1970
