I put a griffin radiator in my 428 about 8 years ago. The radiator includes the transmission cooler at the botton. It was part of a group buy on a mustang board with a good discount. It fits into place with the existing brackets. The connector for the tranny lines were in the correct position. The only issue is that it is a little wider than the stock 24" radiator. It does not leave enough room for the aftermarket fan clutch which is the typical replacement. I had to get the original fan clutch rebuilt which took close to a year. The replacement fan clutches are wider than the factory original.
