upgrading LCD for higher resolution...

I have a Vostro 1500 w/ Nvidia 8600m gt.
Today I dropped it while running and cracked the LCD display.
I hooked it up to an external monitor, and everything works fine, so it's just the screen that's messed up.

I've decided to try and use this mishap to upgrade my res from 1280x800 to 1680x1050.
Any LCD for a Vostro 1500 should work right? Can I use the original inverter for a WXGA screen on a new WSXGA+?
