I've never removed a backglass from the lower stainless steel trim.

I have a Barracora backglass, and the trim is really clamped on there good. In contrast, the new trim I bought doesn't "clamp down" at all, so I layered the friction tape a bit to get a better hold. http://www.marcospecialties.com/pinball-parts/P-6242-107

1) What's the best way to remove the old one? (I'm thinking I should run an Xacto along the edge to minimize paint lifting? -- is that good advice? But I'm rather sure the lift is clamped down hard onto the glass, it won't budge.

2) What's the best way to secure the new one? Am I expected to "clamp it down" a bit onto the glass? I'd be concerned about scratching the chrome, or having a mark where I put force on it.

thanks,

I'd love to see a pic of what this might look like.

Ty, I'm just wondering what this looks like. I realize there are no pictures to take, but wondering what a good contraption would be to help suspend the glass...
