So I have a part number for my BX2680 but I can't find specs for it. It's a ' plug'.. part number 16683-96020. I think it's either a 3/4 or 1" NPT. Maybe I could measure it.. much bigger than 3/4 would have to be a 1" plug right? But for my future research..say, bolt sizes. I would like to have access to that resource Thanks
