Trying to find a chart to decipher the numbers on a couple sets of bases.
2 are marked 33, 1 is marked 1X and the last is a 2.
Any help would be appreciated. I’ve had them for a decade and can’t remember what they came off of. Got into the habit since of putting parts in sandwich bags marked with a sharpie.

Call them. The guy that answers the phone is very good.

You might be able to narrow it down by measuring hole spacing as well.
