Screw size/type for inner rear wheel tub splash shields

[Mhussnatter]

Good morning all. Wondering if someone can help me out with the screw type/size that I need (looks like three on each side) to mount my inner rear wheel tub splash shields? I have searched the forum but could not find an answer. Backstory..... I had my truck in a shop and when the did all the disassembly they did not bag and mark all the hardware. UGHHHH!!! I now have the truck (pieces) back and we are putting it back together slowly. I am trying to buy new hardware when needed and then with some of the hardware it is still not that rusty and usable. Unfortunately I don't have a donor truck that I can pull hardware from or refer to for screw size/type etc. Since I am on that topic where is the best place to purchase an assembly manual for the 69 C10? Thanks so much guys. I will try to put together build post for my truck. It has been a work in progress for sometime now but it is coming along slowly.
