55 GLASS TOP (12/14/2015)
Seems like the one I have came in a ford parts bag appears to be made in america , the one my friend has is
made in china and the word "top" is stamped in and when you put the stamped word "TOP" on to the hole is on the bottom. That is what is going on.
I have come across the replacement or offshore adapters that had ‘TOP’ stamped in the wrong location. As long as the oil holes are placed at the top, you should be good to go.
