Where the hell can you get orings for an aftermarket Ford AOD trans filler tube. I have ordered from everyone from ebay to mcmaster carr to fastenal... What is an old mean to do?

If it is an aftermarket filler tube then the obvious choice is from that manufacturer if that information is known. If that info is not know and you do not have an old o-ring that came on the tube to go and have matched then I would say its time for a new filler tube.

Do you have the old O-rings to measure?

Take the AOD fill tube to the parts store or your local Ford dealer to match up the O-ring. Add a little RTV to it when you install after cleaning the transmission fluid off of the tube and the top of the hole where the stick goes into the AOD. If this has to do with your gasser, it almost looks accesible with the flip front open.

Besides the auto manufacturer site, what about also taking the measurements of the dipstick tube or old o-rings specs to a company that MAKES o-rings - that may not be too expensive to find an oil ring with that diameter -
