I went to install my new CPR backglass and it initially didn't fit. I was able to get it to fit by leaving off the side trim. My original translite glass is 27" wide whereas the new backglass is 27 & 1/8" (as it apparently should be). I emailed with CPR and I appear to be the only one who has reported such a problem. So it looks like my backbox is a smidge narrower than normal. I guess that such variations are not unheard of.
The new glass is still a big improvement as my old translite isn't that nice. But I may want to do something to conceal the side edges of the glass. Maybe a thin strip of black tape applied between the screening and the edge of the glass. Anyone else have to come up with a similar solution for a backglass?
