OUCH! That could have been disastrous! Glad you're back up. No worries on the slight delay.
OK, so they're the same. Nice stuff, for plastic!
I have scrap Plexiglas as well. Plexiglas and Polycarbonate are great for quick prototype and proof-of-concept pieces; although I prefer to work in aluminum (also brass and lead-alloy steel).
I'm going forward to an aluminum chassis, I might even retrofit the Creepy Hybrid's chassis with the additional servo body cutouts and threaded holes.
I'm still kicking around the idea of threaded servo mounting holes vs: matching slots. Threading 20 or so holes may run your costs up, and not be practical for production.
One thing I became acutely aware of was the dependency on the thickness of the "bracket" material of the LPA (as I'm sure you're aware). When I "ported" the LPA into my chassis design, I came up with a mismatch in the axial alignment of the gears. No surprise! My chassis is thicker then the LPA bracket! The solution, of course will be to mill out a pocket to adjust the LPA bearing height to match the lower-seated servo. No problem! However another machine step.

Lexan is a trade name for polycarbonate.
Polycarbonate: Lexan, Macrolon
Tough, bendy, not brittle...
Tough but brittle...
If I were making a single panel as a chassis I would probably go with 2 1/8" panels glued or bolted to make one stronger part, or go with 0.09" aluminum.
