'66 glovebox liner fitment

[Rust-O-Matic]

Anybody else have trouble replacing their glovebox liner with an aftermarket one? It's the correct one for my truck (with A/C), it's just a total piece of crap.

I couldn't get the passenger side edge sandwiched behind the hinge bracket, and the lower front edge is nowhere near inserted under the lip like it's supposed to be. You can see the gap in the pics. No amount of smashing or swearing could finagle it into position.

Are there any alternatives, like folding one out of sheet metal or something? Or maybe a particular brand that fits better? What have you guys done?
