Temperature sending unit

[stickman77]

Can anybody recommend an aftermarket temp gauge sending unit ('69 440 w/rallye gauges) that is the correct ohms as the stock original. It appears the aftermarket ones read too high. I currently have a NAPA. Any ideas on how to get the gauge to read correct? My gauge has been rebuilt also.

I just went through this same problem. If you look up this subject, my post shouldn't be too far back. Bought an oe one from a guy on here (whose name escapes me) and it works great...
