Hello I am brand new to this website but have found some great info on here. My question is I am currently restoring a Glasco slider and was wondering if anyone had some specs for the rack. Someone just cut out the middle of mine to make it free vend but it still has the flapper and outside rails attached. Rather than buy a new one I figured I could just remake the pieces in the middle and the two pieces that hold these rails in the middle. I would like measurements for the length of the rails, how much space is between each rail, and the measurements of the two pieces that hold the middle rails in place. Thanks a lot!
