When you come to put the inner primary case back on you might find there are no dowels to align it and nowhere to put them anyway so use the outer bolts wrapped in tape to pack out the mounting holes until the sealing fasteners are tight.

It sounds much worse to do than it actually is. Worst bit for me was getting the parts. Give me a call if you get stuck.
