Does the distributor mounted TFI Module need to be tight against the distributor body, like a good electrical connection?

Both the threaded holes on the body are stripped out so I cant tighten them. I was going to get a bit longer bolt and put a nut on the back side of the hole I can. The other bolt stays in the hole just wont get tight. Would this cause any problems?

 

There is no electrical connection between the TFI and distributor mount. The mount acts as a heat sink. A poor mechanical connection between the two can lead to the TFI module overheating and causing other issues. I would suggest making sure there is a good coating of thermal grease on the back side of the TFI before tightening it down.

 

Tap the holes out to a bigger size and screw it down.

 

Like dialectric grease? Thats more for connections, what exactly is thermal grease?

Yeah I was debating on that, Id have to go buy the right size tap though and Im trying to keep this cheap as possible since Ive dropped too much money in this pickup already

 

Another TFI cost a lot more than a tap.

Thermal grease is not Dielectric Grease. Thermal grease is for heat transfer and is white in color. Dielectric Grease is more or less clear and is for corrosion and to keep spark plug boots from sticking.

You can get Thermal grease at Radio Shack.

 

The issue I fear has been described, save 1, Too much movement could cause it to catch inside spinning components and shred your Distributor guts (not good) I would follow the advice the others have already given.
