The emissions sensor is on my car, but the scoop thermal switch is missing.

Any idea where I can find one?

I'm starting to wonder about my car. Missing that control and I think the harness. My door panels say Ventura, not GTO, I know someone put it together, but starting to wonder if it really is a GTO.

Stuart, It's possible it was converted to a GTO...fairly easy to do. You should order the PHS, that would tell you for sure. I wonder if there was a separate GTO-only under hood wiring harness from the Ventura II.

Dennis,

PHS is on my to do list.

That thermal control switch is used in lots of GM applications. Gotta check my stock, probably have a few. Used to throw those things away. Now some guys are asking crazy money for them.

I can just use my TCS feed switch, it's the same, and I'm eliminating EGR and the vacuum advance controls from my car, so I won't need it.

What are the first six digits of your VIN #? From 1st thru 5th digiit, should be 2 for Pontiac, Y or Z for base or custom Ventura, 17 or 27 for hatchback or coupe, B for 350 cu 200hp engine, 4 for 1974. Ex. 2Z17B4???????.

I have had a 1974 GTO in my possession since it was born in 1973 and my VIN is 2Z17B4....... I know the K for the 5th position is listed as the 350ci 4bbl, dual exhaust for 1974 Pontiacs, but I haven't seen a 1974 GTO VIN that doesn't have the B engine code in the 5th position, but maybe there were some produced with a K in the 5th position of the VIN..

Hope this helps with deciphering if it is a '74 GTO.

I'll be back at the car's location this weekend and will be sure to examine the VIN.

The engine appears to be correct. It has screw-in studs, certainly appears untouched. Who in the world would swap in a GTO 350 in place of whatever else was in there (and again, it "looks" untouched) considering all of the other options around?

There isn't a lot of money to be made turning a 74 Ventura into a GTO, at least I don't think there is.

Okay, just read the VIN code from a document that I have.

Mine is a fake!

M engine code, 350 2 barrel single exhaust.

Oh well, less of a concern as the 511, etc. goes in it.

Also, forget about maintaining the column shift because it was unusual!

A/C will stay, but no worries about altering a survivor.

Was so excited about getting the car, never checked the VIN before shipping it.

Lesson learned!

Stuart
