Earl.....they are cheaper.....but right now you might wanna check out the special that Trigo is running....they're offering a complete set of wheels (pin drive) with knockoffs and adapters for $1500....not too shabby.
But to answer your question, there are tons of replicas out there like you're talking about.
www.team3wheels.com is one....
Compomotive has a Cobra replica wheel...
PS Engineering also has one....I recently ordered a set for my Cobra.
Do a search on
www.ffcobra.com for their wheel gallery.....you can check out all the types of replica wheels in both knockoff and bolt on.
