in the process of winterizing I did a pretty solid job stripping the two plugs (I believe the manifold and oil cooler) on the side of the engine. In my defense they were pretty beat up when I got it and I knew it was only a matter of time before they were toast. Problem is I'm not sure of the actual name for those plugs and my selco doesn't seem to list them. So in order to fine replacements I would have to start there. I'm also wondering if I can just find thread matching bolts to use in their place? the One off the manifold seems to have a hole in it where it could work as a drain if turned the right way, but does this matter?
