I am building a VERY faithful copy of a '68 Hemi Dart. I have a few questions.

What size tire was correct? Brand?

Was the underside of the car painted, or was it primer like the rest of the body?

What was used as a rear package tray/cover, and did they use the standard "board stock" behind the rear seat?

I know the front was van seats and there was no back seat, how did the carpet go?

Where can I find more info on this car?

Thank you for all your help, This is an awesome site!!!
