Ugh. Gauge & temp sending unit question

[4thgencreamsicle]

Alright. Working on my 69 c10. We went to replace the spade type style temp sender with the correct button style to work with my original gauge. Ran into the problem that since this is a newer engine (mid 70’s if I remember right), the temp sender is too big for the port down by the manifold. There’s a plug in another port on the top end, that looks like the right size,but I think I remember reading somewhere that it’s not a great idea to use that port (by the thermostat) because it’s more likely to overheat before actually telling you it was (?). I don’t know, is that a problem? If so, how are y’all overcoming this size issue.

The hubby and I are also discussing just getting new gauges since we also can’t seem to source any resistors for the back of the temp/fuel gauges and from what I can tell it will only get harder. My question in regards to that is if I were to get new gauges would they use the newer spade style temp sender or would we still need to sort out that aspect.
