1966 barracuda formula s

In '66, the package codes were under the E and F. The E packages I'm most familiar with are the emission packages (such as the C.A.P.) I suspect that the suspension package would be an 8 under the F letter. 7 under the F is the Formula S package.
Thanks Mark. I haven't dug into the 66 yet it's in my barn waiting to see daylight again.
