Finishline is a great place to get parts. I've gotten many things from them to complete my car. You might want to try Mustangs Unlimited as well. They cater mostly to the Mustang crowd (thus the name) but they do carry many items that you can use on your Cobra. They have stuff like steering wheels,emblems,shifter,valve covers,air cleaners,etc..
Also, Tony Branda is another source for Cobra parts. Check them all out and then compare prices, that's what I did.
