First of all, check the FAQ. Then try www.rallispec.com
, and www.axispowerracing.com
. You can also go for www.copartfinder.com
and try to source the car yourself. Prices are often blown out of proportion buying from a yard though. Your final option would be to find the local auto auctions and buy one for yourself. Many of them are private, requiring a dealer's license but some are open to the public.
