Intake manifold bolts

Can anyone tell me the size of the intake manifold bolts on 03 hemi? Just plain old stock bolt size. Seems local auto parts stores can't get them. Don't understand it they are just bolts. Hoping to head down to local fastenal in the morning

M6-1.0x48mm are factory specs for the original bolts themselves. 45mm long bolts work as a replacement length...

Awesome! Thank you

Edelbrock has them.

I went to local store and paid $4
