I have my RFM against a wall and it comes out 52" & the glass is 42". After checking closely I don't think you could remove the glass with less than 91" and that would be tight. Maybe a SC will fit

p2k glass isn't any smaller than regular glass. Only reason the machine is slightly smaller, is because the playfield goes all the way to the back of the machine. you don't have that 3" of gap between the back and the back of the playfield.

I measured with a tape measure on the ground as I slid the glass out until it cleared. That is a measured absolute minimum you would need...sorry

You can modify the plastic mould on one side at the bottom.
When the glass slides all the way out and hits the wall, mark the side rail, then cut and remove the plastic mould under the rail.
This means you can slide the glass sideways at this point and lift the glass out.
When the glass is in it is not noticeable.
I have had the same problem in the past and used this method to fit in more machines
