68 cuda fender question

Hi, my name is Scott and I'm currently working on a 68 barracuda fastback. I seem to be missing the inner wheelhouse of my front left fender. ive looked through several sites and cant seem to find what im looking for. It actually looks like a wheelhouse however in various websites they offer look completely different. I dont want to buy the wrong peice...so can anyone help in this matter.:violent1:
There is a metal sheild at the rear of the fender that screws to the firewall/cowl area. They have a rubber weatherstrip stapled to the edge where they meet the fenders. There was a option that the dealer offered but they were red plastic liners. No way you will ever find those! The replacement shields are expensive. You can also use the plastic shields from later model A-bodies too.
