Okay onto initial dremeling and test fitting and checking for bolt head clearance. Im using M7x1 Allen bolts here that I will use to attach the adaptor to the case.
You can see its close to flush here but not perfect. needs more dremeling
Here's a look at the adaptor to jug gasket after initial dremeling. If you envision in your minds eye, the charge will be allowed to bleed between transfers, but will not escape out or into coolant passages, so we are good to go!
