Going Radio Crazy- 70 GT-500

I currently have a 70 Gt-500(1515) w/ am/8track radio(D32ZA-19A242AB ) the bezel has been modified by cutting the upper part of the opening about 1/2 inch for clearance for the face. The car owner found a NOS am/fm 8track on e-bay. It is a Frontier(brand) w/Ford CCR-721 printed on the box.

The problem is I am going nuts trying to make the fm radio fit w/o major mods to OE bracket or the new repo bezel.

Does anyone know if these are the right radios for this year model(either one) and if so does the am/fm 8trk require a special bracket and/or bezel.
