I am using a Champion 22" radiator and needed a shroud too. Bought an OE style one from Mancini Racing and had to modify it to fit. There is a thread on this forum on how to do that. Basically you need to cut the shroud in half and remove a little at a time until it fits perfectly. Cutting it in half makes it easy to remove too. You will use a piece of aluminum and screws to join the top and bottom halfs. Mount it to your radiator support by using plastic push pins.
