Small block hei distributors

I'm not sure about clearance on a Duster.. but the aftermarket big dizzy GM HEI parts are just like the units you'd find on a Chebby internally. I bought mine on Ebay for under $150.. comes with a set of not horrible plug wires. Ran fine out of the box. Only issue was excessive oiling up top that a lil RTV fixed easily. I replaced the module and coil with Pertonix FF3 parts.
