Magnum head drill jig

I bought a throttle/kickdown bracket for my magnum's intake on ebay. It worked with the stock '73 Duster's 4 bbl. throttle cable and kickdown linkage. It was around $18 and I think Mancini Racing has them also. I used the Lokar cables on the first Magnum head conversion and I'll probably use them this time around on the current '75 Duster project because the kickdown linkage is hard to find around here.
