I was originally going to use a Stack water temp guage on my S62 conversion with an M12 sender, however, I've had a change of plan and have gone back to using the standard guage. I now have an M12 x 1.5 thread tapped into a (welded) boss on the thermostat housing which (being lazy) I could do without removing/re-drilling/tapping. So, is there anyone who knows of an M12 sender which will suit the stock E30 guage?
TIA. Dave.
(I thought I'd ask here as there's possibly more chance of the motorsporty types having similar expieriences..)
