I have the senders for a 85 911 oil temperature and pressure combo gauge. Since they are not going into a 911 engine I am looking for the thread size. I have not been able to find them when I have searched the web.

Oil temperature sender is 911 606 112 00.
Oil pressure sender is 911 606 135 00

Thanks Irv

Sears sells a thread measuring tool but if you're cheap like me (although I do have the thread tool), you could take the item with the thread questions to Home Depot or local hardware store and physically match the threads with ones in a package that's labeled. When you put the "peaks" of one threaded item in the "valleys" of the known item, you'll see the match/non-match. 'Course you know it'll be metric ....
