'68 Dart Instrument Cluster Refurbish

I'm fairly satisfied with how the bezels have turned out so far. I've been masking and painting sections with satin black and silver argent. I've only got the instrument section left to do. The part that has me stumped is the plexiglas in the speedometer/guage window. It's scratched, cracked, clouded, etc. I haven't found a way to remove it without totally destroying it, and the plexiglas cleaner/polisher won't do the job. It seems like its glued in place. Then, even if I got it out, I don't know what the next step would be because the plexiglass has a slight curve in it; it won't be replaced with a plain flat piece of plexiglas. I guess I can go to Gcar or Instrument Specialties as suggested above, but they are pricey as hell. Plus, the work I've done so far wouldn't match. Has anyone on here ever replaced the plexiglas lense successfully?
