So the top 6 are the block and the head, I think the large silver one goes somewhere in the bell housing, and one of those small black ones is the drain plug for the block. What are the 2 small brass ones? And the other 2 black drain plugs? I've been trying to figure this out for a week. Thank you!
Hmmm....when I have replaced the freeze plugs in my 98 and 99, I don't recall using any small ones, just the big ones along the side and the one behind the bellhousing. Looks like that kit applies to a wide range of Jeeps years so maybe those are applicable for a different Jeep application?

The 4.2L uses the smaller ones along the side of the block. Big - Small - Big - Small - Big
