on one of my new spacers the threads were cut on an angle so the plug fits in on an angle. I know that you don't insert the plugs all the way just a few threads to seal the hole. I just want to make sure that it won't leak.
without seeing it its hard to ay, myself I would take it back.
last set of merc risers I ordered had to go back due to serious dings on the gasket surface.
