67 Barracuda - question re: carpet cost and considerations

I agree.
Notchback should be less than fastback.
I just painted the rust and bare metal and use factory type replacement carpet and backing.
Structurally, the rockers are important.
Overall fastbacks seem to be a little more rigid than notches, but that doesn't change the importance of the rockers and how they tie into the front and rear channels that create a frame structure. You'll see how the leafs are attached in the rear and the K frame and torsion bars in the front. The transmission cross body channel holds the torsion bar anchors. If those are rusted - that's a serious issue.

What else to know. More '67 were made than '68 or '69 Barracudas. They also have several one year only features: Lockstrip weatherstrip for front and rear winshields, idler arm is stud mounted are two to know about.

You can look at the dealer data books to see what was standard and optional
The 1970 Hamtramck Registry Library Page (1965 - 1969)

Most wear and tear parts are available. Some things you'ld think are common and cheap, like defroster duct hoses, are not.
