All set. There were two water temp sensors. I ended up using the one in the intake manifold. Was able to bring it in to NAPA and they found one (will have to check p/n). I only had it on the road a few days when I noticed the rear frame was shot. Took months to get it back going, then (see other thread), the rear brakes went out (only driven it a few hundred miles). Now I'm in search of fuel tank and sending unit.

Here is a highlighted picture of cracked cover and backed out bolt. Luckily an easy fix. Just haven't gotten to drive it much since :-(
