Radiator support opening

As it turns out Plymouth was using a different size radiator support for a small block vs a big block engine configuration.  And as fate would have it this car although it had a 383 in it must have started off as a small block car because we actually have a small block support here that is for a 22 inch radiator and we will be running the much needed 26 inch radiator for maximum cooling capacity.  Luckily we caught this at the last moment so making adjustments and reshaping the core support to match the radiator can be done in such a way it looks as factory as possible.  Would not have been easy to change it after paint but glad we caught this detail.
