Screw/bolt size

Anyone know offhand the size/type/length of fastners used to attach the metal pedestal that the spare tire rides on? I have two, they are the shorter ones I think, they look like #12x3/4 long. Any ideas on the other two? I tore everything apart in a panic a while ago and of course didn't package& label things:doh: . Rats. I am learning my lesson!! Thanks for any help....

Yessssssssssss!!!. I found the missing bolts!! Heart medication has a habit of leaving gaps in the memory..... :wierd: Alls well that ends well. Thanks anyway. Hope I didn't waste anyone's time.
