Reverse Light Switch

Post by ranger372 »

Hello All, Question, Reverse Light switch on the underside of a 4 speed Transmission.....What is the thread size? Believe it is a NPT size. Switch is leaking and want to replace with a plug. Car is a '65 Corsa :helpsos:
Thanks,
Steve D.

65's are smaller than 66-69's. IIRC 1/2"-13 threads for '65. Clarks has repro switches.

It isn't NPT. It is a straight thread.

Thanks Guys, So it's a 1/2"-13unc bolt. Short as can be - only as long as the switch threads are. Brass compression washer would also be good.

Yes, def keep it as short/shorter than the switch. Anything longer will block or interfere with moving parts inside.

There was originally one plastic washer used along with the switch. Some who removed/replaced the switch did not notice the embedded plastic washer and failed to remove it. When they purchased a replacement switch, they installed it with the new plastic washer it came with (accidently stacking two washers on top of each other). This caused too much spacing and made the switch inoperative, until th 2nd washer was discovered and removed.

ALTERNATIVE...
"Fix It Kit" The old switch stays in place. We supply all the wire, screws, connectors, bracket, switch & instructions to add a switch that mounts near the shift tube (like on the 1960-64 3 spd.). For 1965-69, the switch mounts back by the front of the trans by shift tube. Takes about 1/2–3/4 hour. "Fix It Kit" C8379
