I would say the thing that took the most amount of time was getting the lower mounting ear bolts torqued. Not that it was impossible, it was a bit annoying and I ended up taking the rear down tubes off of the sump to get at the nuts.
I am happy to say that everything fit first try. That said, I am going to pop the engine off and re-weld my cross bar on the engine mount. I previously lowered the cross bar in order to clear the sump. I will admit, that when I measured everything up, I never fully mounted the engine mount to the engine. I was looking for about 1/2" of clearance, which I did end up getting... And then I torqued the engine mounts and took the weight off of the engine. I ended up with about 3/32" of an inch when all was said and done. While that may be fine, there is no reason not to re-weld this because it is going to take me all of an hour to take the engine off and put it back on. Plus, since I have procrastinating some building I have been doing a lot of 4130 TIG welding to keep my skills up. 1/16" 2% ceriated tungsten with some 1/16" ER70S-2 does a much better job than my previous 3/32 setup.
