hey guys-i've got the adapter off the truck & have removed the 36mm bolt. I don't see any o rings anywhere! do I need 2 remove the oil filter? where do the 2 small orings, large oring and copper oring go? any help would b appreciated the weather is rollin in.

I replaced mine, and there wasn't much mystery... I did have my oil filter off. Let me try to find pix.

The 2 small o-rings are on the bolt its self if i remember correctly
