Fan shroud bolt size?????

[Davesmopar]

I am installing a fan shroud, not been using one, but it's getting hot out now.....

I have a master tap and die set but nothing fits the radiator holes for the fan shroud... before I make my own holes can anyone tell me the correct bolt size????

76 Roadrunner 360 radiator...

It's been a while since I've had one off but I think it uses the bolts that are more like screws.

You are correct. It uses what I call sheetmetal bolts. Not sure of the size but the head of the bolt (technically screw) is 3/8".
