Documentation for claiming CNG tax credits

[kstoker]

Any idea of where I can obtain documentation of OEM CNG optional equipment costs for Chev and ford vehicles? I am specifically looking for 2001 chev cavalier and 1999 F 250 P/U documentation.

Have a look in the Chevy and Ford forums. I posted threads in each for people to post their window sticker info. What you're looking for may be there.
