According to my information the 56 Desoto batwing which looks like the one on Ebay will not fit over chry. carbs as the spacing is different,also G.M. batwing or Packard will not fit.Cadillac batwings have two small holes on top for chrome " V ".I was very interested in this carb-batwing set-up but I don't think the batwing which is definitely not a chry.anyway will fit over carbs.
