Front Carb Bolt Size

Shot in the dark dept

I'm missing the two long bolts for the front of my Rochester quadrajet carb to bolt it onto a early 70's Chevy 350 engine. Anybody know what size/length these longer bolts might be? Hope to be able to get them at parts store.

Greatly appreciated to see if this old beast will turn over.

Thanks, Dave
