First off, I checked and the new stack fits just fine.
Then, I finished off installing the CHT, EGT, tach, and speedo. It's tight in there and I still plan to add LED's to either side of the speedo for the turn signals, but if that doesn't happen Day One, it won't be the end of the world.
I'm may eventually re-fab the CHT/EGT bracket out of thicker steel and will adjust the alignment of the gauges a little when I do, but I can live with what's there now, so the emphasis is on "eventually."
Another productive workshop session. Too bad my Mercato order doesn't seem to have shipped yet. Still time for it to arrive Friday or Saturday, but I'll be bummed if I miss the weekend because I'm waiting for a part due to my own mistake.
