I have looked just about everywhere that I can think of to find all of the information on the oil cooler bolts for my 96 Blazer. Long story short, I bought a project from my brother (I know, I'm stupid). The bolts for the oil cooler lines are missing. I have found the gaskets and the lines everywhere but I can not for the life of me figure out where to find even the size of the bolts. I need to find the bolts that mount the adaptor to the block and the bolts that mount the lines to the adaptor as well as the bolt from the lines to the filter housing. Any information that you could give me would be great.
