Can anyone help me , I have a 65 MERCURY Econoline p/u , & my tailgate isnt up to par & is too far gone to save. I need a repairable tailgate . I tried to save the original but it didnt turn out too good . Merc's were ONLY available in CANADA , mine is #310 of ONLY 1291 made in 65, this info was provoded to me by Ford . Im running a Shelby 302 /600cfm DP Holley, C-6 narrow case, 9" Ford / 350:1, couldnt get my Hedman equal length headers to fit so had to use mustang shorties , would really like to be able to use those BIG tubeheaders , as I am dumping it out infront of the rear wheels via 4" BOOM tubes /flo-pro mufflers, Really rumbles !!! Can anyone tell me , if i can get GT-40 heads to fit under the doghouse , my exhaust port line is below the floor now , but I have NO extra width inside the doghouse , Original heads just "touch "the isulation now.
