screw size question

[warbird]

I have a 1994 gmc 2500 regular cab, I am freshening up the interior. at work right now so I cant check. does anyone know offhand what size (length/diameter) the screws that hold the sill plate down are? I'm wanting to order some stainless replacements

I think they are like 1 1/4 in or something. Philips head sheet metal screws
