5th pic from the top.. the bolt holes for the thermostat housing don't look healthy. They look egg shaped on my monitor.
Are there threads in those ?
My apologies. I wasn't seeing the photo properly. What looked like weird rusty bolt holes yesterday is actually rusty bolt heads this morning. 2D photos will do that sometimes. Reminds me of a time when my avatar was a door mirror and someone thought it was a Penguin. Anyway... Good luck with sale
