Sorry about the bad info on the distributor - thought that it fastened to the block.

Do EVERYTHING you can to get the temp probe out without damage. The probe, wire and guage are all one piece. So you would need to find a new (ga$p) or used piece, and take the instrument pod out and remove the back to put the replacement in.

Get some PB Blaster and a pair of good vise grips. WD40 is marginal for unsticking threads.
