Not much to show, but a real pain to do. Removed two large washers that I had placed under the top two attach points on the engine mount to the firewall. It appeared at the time that these washer were required, and I never removed them, but instead hung the engine for a test fit and didn't think it would be a big deal to do later.
It's later and it was clear that fitting the cowl would be done wrong if they were not promptly removed before moving forward.
The problem was that I chose to not remove the engine and instead removed the washers one at a time, by removing the bolt and needing to reinsert it, (two bolts). And I knew that failure to insert the bottom center (pilot side) bolt near the main gear attach, would also be wrong. This required removal of the bottom left (pilot side) bolt, insertion of the center, then forcing enough pressure to align the outboard bolt and insert it.
This was done over several hours because of the difficulty of 'moving' the alignment a fraction of an inch to insert the bolts through the firewall.
