Ok guys, I need help (again)

There are 4 bolts to mount the main drive pulley to the E-shaft hub/whatever you want to call that. it should be 12mm in size. I tried to find them in FSM but I can't locate it ...

where did my 4 original bolt go? I don't remember exactly but I think I threw them away cuz it's all rusted. thought that I can locate them in FSM easily ... I was wrong

or

can I just use some Metric Grade 8 screws with M10 washer ? M10x16mm seems ok,

 

Those bolts are 6mm x 1.0, maybe 20-25mm long (citation needed).

 

and bolt head is actually 10mm

 

I believe the 4 bolts on the water pump pulley are the same size as well. ^ is right, they're 10mm. Steal them from something else, they're used quite a lot.

 

I used extra oil pan bolts. They're super short, but they work for me because I don't have any other pulleys besides water pump/main/alt.

if you do, you can use an oil pan bolt as an example and just get a longer bolt.

 

bought a box of screws from Autozone for "Asian Vehicles", made by Dorman.

I think it has M10x20mm or 25mm. not sure, need to check.

 

Metric bolts are labeled and sold my shaft diameter and thread pitch X mm in length. Meaning they are 6mm shafts with a 1.0mm thread pitch and 20-25mm length. Awful common any hardware store should have them for next to nothing
