Tell me if what I do is wrong . I have done it dozens of times . Back when junk yards were full of 80s ford products , I would takeas many as the day would allow , just the gauge . I was amazed that ford changed nothing in the gauge , more plastic of course but same looking design . All I did was swap the guts from the 80s ford gauge into the 40s factory gauge brass cup and faceplate , and needle . Then I used a aftermarket ford ohm sender and the factory 1980s cvr ( constant volt reducer ?) . Of course all this was because the original sender was gone or bad .
Havent had an issue, in fact I just did it last week on my new to me 41 .
Have I been lucky or should it just work like it has been . I can send pics of internals comparison to someone .
