Years ago Bob repro'ed the 55 to 59 shroud assy. Some had the cut out for later 56 to 59's for the top Radiator hose . 55 to early 56 had the first design not having the cut out as seen here on a original 55 vett. I only know of ZIP that still sells the first 55 design with no cut out. I've seen many restored 55's using the second design and thought I would let owners know about ZIP that still has them because most supplier's still list them as 55 to 59 as tho they are all the same. Bottom pic is ZIP's
Still no one sells the the bottom piece of the shroud that support the lower one , that' why the lower piece has those two little holes and if your missing the screws to hold it your missing it.
