Hi, folks! It's been awhile since my last post, but it looks like I can finally begin the resto of my '67 standard coupe this fall/winter. I have some questions, though, so here goes; 1) Is it possible to cut a 2-3" x 9" hole in the firewall below the export brace and use the cowl as a source of supply air for the carb? 2) Where is the difference in length between the Mustang and the Cougar? 3) Is it possible to convert the wiper switch to a pulse/delay while still using the stock dash lever? Thanks for your time and consideration.
