As I mentioned earlier, I am going to need to fabricate a custom bracket for the intermediate drive shaft.
To get started I inserted the intermediate drive shaft into the trans-axle only to discover a new problem.
I used a sharpie to outline where the drive shaft flange conflicts with the adapter plate. I emailed my contact at Canada EV to let him know about the design flaw. He offered to modify the adapter for me if I want to ship it back to his shop.
I declined and opted to modify this myself with a handheld angle grinder.
