I have not seen people do a 99-00 Rear bumper onto an EG.
The Front clip can be done for not that much money. The biggest pain is swapping the core support to a EK Core Support. But if yours is wrecked you want to swap that anyways.
Some people say you need to cut and weld fenders in the middle however you can just cut the EG fenders to fit the EK headlights.
Heres a link to a guy who did a "Budget" 99-00 EK Front clip on an EG. If it was one color it wouldn't look that bad.

Since your in Washington, a good place to get OEM style replacement parts is certifit. Some people say they wont line up correctly however I think they blame their bad body work on their parts.
I have used certifit parts and had them line up 100% and so have a few friends of mine. If you working with a car with a wrecked front clip it will take work getting it to line up but once done it wont pretty good.
