I don't know the name of these two parts, but they're small cylinders, with a slot down the length of them (like a piece of metal folded into a cylinder.)

I believe they were in between the LIM and the supercharger, and I believe they were just to help align everything when reinstalling. They aren't a critical part, are they?

I forgot to use them, but the supercharger's already torqued down with the new gasket. Should I just leave it alone? Will the gasket be ruined if I take the supercharger off again, or will it still be OK if I haven't run the engine?
