Looking for advice: 71 Demon 340,4spd, AC, original metal car

:D your wrong do some research. I'm sure some on here will chime in that know demons before I can get home to show proof.

Can you please PM the proof. I've studied and built nothing but Demons for the last 17 yrs and all the documentation I have states the thin line should be there. I'm always looking to learn and update my references so please me your docs that show otherwise. Thanks!
