This might be a good time to consider ammeter/alternator bypass if you haven't done that already. Related-might consider changing ammeter to volt meter. There are several threads discussing each on this site!

Need to run a wire with an eyelet terminal to the oil gauge. I spliced into the grey wire on the oil light (standard dash) when I did my conversion.

I recall there used to be a "conversion harness" that was available aftermarket for this to avoid cutting.

Rallye dash cars also came standard with the 3spd wiper setup and electric squirters.

Why change an otherwise beautiful restored car ?
