I have a '79 ElCo and just recently joined the site just like you. What size rim, tire, and backspacing are you running in the picture? I have 385 SBC, AFR 227 hears, T&D Shaft Rocker, Belt Drive, Zex 200 Shot, Ford 9", 6**/7** life solid roller, Art Carr 700R, 4:30's in the works and when I show 20" Boze wheels, and when I need to go ??? Not affraid to notch it to make'em fit so what's in the rear of yours and did you have to make any frame mods?
