Quoted from JethroP:
This confirms the same size as my original glass .... 22" high. But the one I received is 3/16" oversized.
Thank you for confirming the size of your glass. I believe the glass I received is clearly not within spec.
I had the same issue with an Abra glass (Ive actually got a c37 glass I havnt even removed from the box). Had to take the vent cover strip out of the head, shave it with my belt sander and put it back in to gain the clearance. I'll pop open my c37 and measure it for you, Im sure the run of 30 glasses were all the same. (Minor plug, if anybody has a c37 that needs restoration I have a pf an bg waiting)
