Quote from: Brian350 on October 07, 2026, 07:35:44 PMNo prob Mike, thanks for the reply. My current struggle is that I can barely get under the dash (69 years 0ld  ;D ) and I can't really see anything (From my limited vantage point) that looks like a circuit breaker. I'm still going to pursue this idea, but I'll need some help...
Taking out the driver seat will help a lot with access. Some of us can still manage without doing that but 4 nuts underneath and the driver seat is free to take out. 

Good point. Or I can hire someone else to climb under there...

1969-1970 Shelby GT350/500 / PVC valve grommet?
October 07, 2026, 07:37:34 PM
The grommet that goes into the valve cover in the picture is really loose and provides a sloppy fit. Can anyone here direct me to the correct replacement grommet for this? (1969 GT500)

As opposed to a conventional fan setup?

Quote from: mr68shelby on September 28, 2026, 12:52:06 AMCheck the circuit breaker mounted just above the fuse box. Pretty sure the A/C runs through one of them. When it trips, it resets itself. They will sometimes get weak with age. Or something is pulling too many amps and tripping it. Mike

Interesting. I'll take a look. Is that breaker easy to replace?

Thanks for asking Cross, not yet, got derailed by radiator and power steering issues, both of which are being solved today. Then I can focus on the AC, just as the weather here cools off!

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!

Quote from: SHELB66 on September 04, 2026, 12:02:55 AMI 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.

Quote from: Brian350 on September 03, 2026, 05:05:56 PMHow 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  If its the typical external then there were plugs originally made by Ford and I think they are or were reproduced.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?

Quote from: Lincoln tech on September 03, 2026, 05:58:40 PMThe 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...
