There’s a lot of fan shroud kits out there, most of which have dimensions. Some have the center opening cut, some are solid and you lay out and cut it. They don’t look very attractive, kind of street roddy, but fitted and painted semi gloss black they pretty much go away.

I’ve also (in the days when you pulled your own) taken factory moulded plastic shrouds and cut and spliced them. Not perfect, but workable. In a perfect world you want to cover the whole radiator, but if you get 80/90% it’s better than none at all. Even a simple circular shroud properly centered around the fan (tip clearance and in/out spacing) is better than none at all.
