The parts from Zenith arrived a day early (thank you, UPS) and so I was able to dive in on my reconstruction project. Sure enough, once my rivet lines were drawn on the new piece, I picked up 7mm of extra length on my project. More importantly, things should line up as designed. The installation went smootlhy and the project was aligned from rear to front by using a self-leveling laser level (as described in my next post).
