Made the temporary spacers. Fabricated the aluminum tubing spacers. Fitted / mated the two bulkheads with the spacers. The process was not all that easy, the bolts are such a close tolerance fit, it takes a bit to get everything in place. After some gentle tapping the bolts fit perfectly. I torqued the required bolts on a few of the flanges and followed up with torque seal.
I also took delivery of a replacement governor Gear / Housing for my engine.
