that setup should work if adjusted correctly.

i have a repop stock linkage on mine, and it works well, and i like the fact that even though it is far from stock, it still looks more stock than not, if you know what i mean

i custom made all my linkage and brackets, as i run a stage V manifold, where the carbs are farther apart, and the bosses on the manifold where the brackets sit don't exist, all the bolts are the same length.

there really shouldn't be any issue getting that linkage working, (i had exactly the same thing on my car when i first bought it years ago), but if you want, i'll post pictures of my stuff.
