Wow! I just went down that same road. The shop finally found one for my J model. They ended up having to change out the temp gage along with the right fuel gage as it was an assembly that couldn’t be easily separated without breaking the temp capillary tube, so I was told. If you have a good relationship with a shop, I find they are better at locating salvage parts than me, and, unlike if I buy direct, with them I don’t have to pay first for something that might not work.
