crazing on the perspex headlamp on a 997

[Roundm]

Has anyone found a source for replacement perspex for the headlamps on a 997 ? Mine are suffering from UV crazing and I would like to replace them.

I know you can sand and revarnish, or just polish if it's not too bad - but UV crazing forms in the middle of the perspex not on the surface.

I've found yellow ones (for race cars!), but not clear.

anyone ? £800 per lamp for replacement is a bit mental

Thanks
