Can you be more specific about what you're trying to do?
Engine/performance, suspension, wheels??
The Spectra is about the same as the Elantra, if you use that for your parts search, you may get better results.
There are a number of things that are interchangeable between Tibbs and Spectras. Sway bars, end links, struts and radiator hoses are a few things that I know of. Mosey on over to Streetkiaz because there is a lot of info on this subject.
