    Muck around in here and see if you can find one to your liking.

    Rock auto will also have them

    Not sure what SI charges but it's still good to support our venders.

    As far as adapting a smaller unit, to me, as long as the sensor is inside the block/manifold/head and has the proper resistance, why not. I do that on most aftermarket manifolds as they come with larger NPT opening than most senders.

      Are you sure it's not 1/2 NPT? Which connector style? Screw on with nut, single blade, double blade, slide on T. Most likely a Stewart Warner item, probably available from Summit and others as a replacement. Dual post ones go for about $25.00 single $15.00 for a Chevy impala 283.

          These are what I use. Just find the one that fits your application and motor on.

          I agree with Fred, most likely a 1/2" NPT but stranger things have happened. National Pipe Thread would be about the 3/4" measurement as It uses pipe ID? dimensions not the threaded dimension. Welcome to the wonderful world of plumbing codes.
