Got a set of plugs from someone here on the Forum, thanks everyone!

I have a set i'd gladly sell.  Removed from my car when I put smog back on.  PM me if interested.

Let us know if you can actually buy something from him. I never had any luck and I'm surprised he's still around if he actually is.

Will do!

I would definitely leave everything on the engine.  It will look naked without.  Many years ago that was the first thing to go.  Then the smog inspections took hold and we had to put it all back on (if we still had it!).  My feeling is that a Shelby engine compartment looks much better wearing everything it originally came with, including smog tubes, backfire suppressor valve, Thermactor pump, etc.  Just my opinion.

That's not them.

How many holes? Best way to plug them?

Depends on what your car is and the system (internal or external) you have installed.  If its the typical external then there were plugs originally made by Ford and I think they are or were reproduced. Of course you will have to choose to leave all the brackets and mounts or to buy new/different ones to hide that the Thermactor system was there. Also for that system and design you'll need 8. One per cylinder

Where can I get those?

The first thing I would do is while the fan is inop check ground and power at the fan , that can be done with a basic self powered test light. Just don't touch anything . If you get both and the fan doesn't work its the fan itself.

Added to check list...thanks...

Don't toss it.  Sell it or save it. It's expensive to replace

I'd leave it in place. You won't get much performance increase by taking it off. If you do take it off label everything and keep it ALL in ONE box and NEVER go in the box to rob a nut or bolt for another project. When you pass the car on the new buyer will probably by that time want a full museum restoration and you'll be able to get extra $$$ for the original pieces.

I had already planned on keeping all the parts, I've done that for every car I've owned.

Understood. I'll save it to go with the car.

Anybody else done this? What do I need to know before I do?

Since day two when the cars were brand new this has been done. Pretty straight forward, remove and plug the holes left from removing the smog equipment.

I have never had a 69/70 with a/c, so these are general guesses.

It could be as simple as crap in the cowl restricting air flow causing the fan to work harder. Could also be lack of lube on the blower motor bearings (bushings). After it cuts out, feel the blower motor to see how hot it is.

Thanks, I'll add this to my check list...

if its the fan that stops blowing. you need a new switch. the relay is part of the switch. if the air cond is not operating, the electric clutch on air compressor is faulty. my guess, try the switch first.

Yeah, the AC blows nice and cold for a while then the fan shuts off, then a few minutes later I can turn it back on again. Compressor is new.

Kinda sounds like a relay is getting hot, and cuts the power. Some sort of an electrical issue. I'd check the switch with a voltage tester.

Hey Vegas! Have I seen you around town at car events?

I'm a bit dense on this stuff, What switch should I test?
