Sorry to hear about your deformity Frank. With me it is usually a fat head!
A great offer, unfortunately for me I have an '85 Impala and those great parts won't fit. My fat head thinks that a 1964-'72 Chevelle kit will work if I can figure out how to stretch a few pieces since a Chevelle 12 bolt will fall in place and bolt to the top ears, it is just a mater of figuring how to adapt the lower control arms and springs; or using the Impala springs and modifying the Chevelle lower control arms. Have you ever given this a moments thought?(adapting Chevelle rear suspension to a cheapo 1977-1991 Impala)
