Ron, a friend of mine has a super nice (& fast) 65 Coronet 500 with the 17"x 5"setup on his RB 512 stroker with 2x4's. Ducted to the inner headlight buckets with mesh covering the openings. Looks really trick & flows good. I know you can't do that with your Charger's concealed head lights, but Spectra makes a firewall ducted unit that draws air from the vents at the base of the windshield. Similar to what Petty did on his 64 NASCAR Belvedere. I'm considering that with my 64 Belvedere. BTW, glad to see you still have your 68 Charger & would be great to get together with Holly's Charger again. Buzz
