What size screws are used for...

mounting the fan shroud to the radiator? I don't have any.

Aren't there studs mounted to the radiator flange?  Mine uses nuts to attach the shroud to the studs - but that's for 1969, and later years could certainly be different.

No studs on my radiator. It has the threaded holes for screws. One of the members said he has the correct screws and is going to give me some. I should have them next week. BUT, even he isn't 100% sure there the right ones. If not, I will get some pics.

I can't talk... my radiator and fan shroud are made in here in Venezuela, and maybe are different way to mount.

they are 7/16 head(actually if you have any valve cover bolts lyin' around they are the same size)

26" Radiator uses a #8 machine screw with a 5/16" hex head.
22" Radiator uses a 1/4-20 large flange 7/16" hex nut
