I have restored a few Mustangs in the past, and there are a ton of sources for aftermarket parts.

Are Mopar parts easy to come by as well or am I going to pay a premium for every single thing? What about aftermarket performance engine parts for a 426 Hemi?

I am considering buying a 1970 Challenger or Cuda, but the wife wont let me mortgage the house for an intake manifold.

Thanks!
