Temperature gauge - mechanical to 6 V electric

My ’46-’54 Plymouth factory service manual indicates that Plymouths through at least ’54 had a “mechanical” temperature gauge.

[Above is from a thread in the truck forum by Royhldn called "Bully".]

 

Question: Is there a 6 volt temp gauge that can be converted for use in a P15?  If I recall correctly, '55 was the first year for 12 volt systems.

[I have a '55 engine in my 46, and rebuilt it with the late model head before I realized that it does not accept the mechanical sending temperature unit. I do have the head from a '49 1st series, so I could swap them out, but I did a lot of work on this later model head - vatted it, bead blasted, and cad plated - so hate to loose that work.  If I can't go the electric route, then I will probably have the head drilled & taped for the larger diameter fitting used in the P15 head.  I didn't want to convert to 12 volts, but I know that would be another option.]

I have an aftermarket sender in my 56 engine, I don't remember doing anything special to install it.  I will take a look shortly to see if there is an extra fitting or something weird there.

Drill and tap it.  I would do it without removing the head.

It would take you longer to swap out the gauge and rig up an electrical one than drilling and retapping.
