Dress down the mating surfaces with a large flat file.  You need flat
surfaces to seal well and clamp the gaskets firmly.

Buy lots of 8 mm bolts.  Get some a little longer and shorter than you think
you might need.  You will use them eventually.  Consider getting stainless
steel especially for the ones that are hard to get a wrench on.
