Stop in for a cup of coffee

I can’t find one. The LA one is bigger and won’t fit. The replacement ones sold by advance auto and classic industries both are the same diameter as the LAs even though they claim to fit the poly. Tried those this week. I’ve got a wanted add up and so far nada
Did you pull the piece out of the block?
Its basically 5/16 tubing with a bubble. Maybe 3/8”.
If hole is undersize, why not just drill it larger?
