Silly basic question of the day two part

[jlemler]

So I was putting on the OEM spring hose clamps for the heater return to the block.  Some how I broke it into two pieces.  I go to the local store by a replacement.  For some reason it is a little lose.  What size do I need for the clamp on the heater return to the block?  I thought it was 5/8s.

On the metal access covers what size screw do I need to attach them?  Does anyone sell the correct ones?  Do they screw on from the outside in or inside out?

Thanks for all the well wishes yesterday

One heater hose is 5/8" the other is 1/2"

The screws are #8 sheet metal screws with a 5/16 hex head about 3/8" long.... 

The covers are attached from the wheel well side...

Enjoy the day with your dad!!!!
