Hi gang:
I have a very old O-320 narrow deck engine that I've been slowly rebuilding. The oil dipstick threads measure 1 1/8" and 12 threads per inch.
For clearance reasons (long story) I needed a extension tube installed for the dipstick. I had a oil tube extension Part # 75761 which had a 1 1/4" thread. I turned down the extension tube to 1 1/8" in my lathe and cut threads into it. This modified tube now screws down into the hole in the crankcase and now I need to find a suitable dipstick.
The top end of this extension tube looks to have 1 1/4" threads in it and my original 1 1/8" dipstick will not screw into it.
Can someone tell me if the newer versions of the dipsticks are 1 1/4" threads? or will I have to find a way to modify my original stick?
I spotted a long dipstick on Ebay which I could cut to the length required if the threads on the cap will thread into my 1 1/4" sized extension tube.

Thanks in advance for the help, Terry.
