Hi

I looked at the 3926 and it says "Gasket Seat"?

That describes Autolite 3926 - 3/4" reach, 5/8 hex, washer seat, street heat range.

3923 is what I was fouling.

The last digit is the heat range - lower is colder.

I'm pretty sure there is a 3924.  I don't know about 3925.

If you don't like or can't get Autolite, I'm sure you can cross reference these pn's.
