I would confidently wager its BSPP but no need to guess. Pull the plug and measure the OD of the thread. The OD of a 3/8 BSPP thread is .656 and easily distinguished from any SAE thread.Thanks, Dan. Purchased.
I have another question. Does anyone know the thread size and pattern of the rear axle housing plug I'm pointing at in the previous picture. My guess is that it's a 3/8-19 bspp, but am wondering if it might be ORB. Does anyone know for certain?
