Nice fab. Don't forget the isolators to prevent cracking from vibration. I use blue pvc load rated grommets from Mcmaster. Just drill the holes in the fan to fit the grommet OD with an ID large enough to accept the bolt with a nyloc on the inside or a short piece of tubing over the welded stud for a positive stop for the nut. I'll find the page for him.

This radiator is a direct mount type (circle track with dzus tabs pre welded form the manufacturer) I got the impression the radiator was designed to be dzus mounted, do you think I still need vib isolators, if so where just the fan, or radiator to frame? the radiator is pn 2020225010 from c&r radiator. I certainly don't want to cause undue dammage, however I want a simple clean install. My mounts are brackets with dzus fasteners 4 places, with oval holes in the frame brackets to allow minimal movement and of course the dzus springs flex a little, let me know what you think. Thanks!
