Yeah I'd say go with the appropriate glass for the model. Hopefully you can offset it (and if it weren't so large, might be possible to repair rather than replace?), but there could be reasons beyond the aesthetic of a quiet ride for using that particular glass as a basic feature. Such as reducing noise from the engine/brakes that might need muffling, or...

I guess that might even be an interesting question for the 2008 TCH thread--is the acoustic-dampening glass an intrinsic part of the model even when it's stripped down, or does it become more of an option in any circumstances? I have no clue what (of the ones that make any sense to ask) extra features on the 07 are there for safety requirements and what are just special features.
