Radiator Shroud

I have an aftermarket Radiator; Griffin Thermal Products 1-26272-X. The current OEM fan isn't a perfect fit and the bottom two plastic bolt flanges are broken off and there is a small air gap on the bottom between the radiator and the shroud.

I'd like to know if someone here knows the correct shroud for this application? The car is a '69 RR with a 440. I've never been a fan of universal shrouds, as my experience has it that they universally don't fit anything.
