This sort of a problem has cropped up in discussion before when trying to fit modern glass into the old window and vent frames.
Not being a glass man I don't know whether it’s just a matter of poor selection on the part of the glass shops or whether that thickness is no longer made.
Either way I would think that if your glass is to thick for the run channel then you are in for nothing but trouble till you find the proper thickness.
