Hey Mike, and Welcome.
AFFORDABLE needs to be better defined my friend, you are talking a 27 Ford.
Rolling chassis is gonna set ya 'bout 6500 depending on the rear you choose. Fiberglass body complete will be about the same, also depending on the interior you choose.
Then you may want hubcaps & a radio, so that will be extra.
You could look at the ads here & dial 888-246-0900 & ask I might be wrong.
