The only advice I can give is get the front and back from a junk yard and get the side skirts from Bill Jenkins -
parts@signaturelm.com That's how I built my "kit" all in all it cost me 1300 bucks (that cost includes shipping, and painting) so get ready to spend spend spend! OR the other route you can go (which you better be on your toes for this) is E-Bay, and the Classifieds, but they come and go fast, and they're very rare, ha trust me I checked.
