The “Alignment Pins” are just simply 10-24 Hardware store variety steel screws with the heads cut off about 7/8″ long. Just temporarily installed by hand a few threads to act as guides. Keeps everything from slewing around and easily removed when you are ready to install the actual ones when everything is seated. Probably could use less than 22 pins but a small price to pay for my piece of mind! Of course shear pins are way too valuable to be used for something like this!!
Sorry, no extra lower cowls for the 20s. I even looked behind my bowling ball collection. Did find some for the 40s and some other stuff I didn’t even know I had.
Hope this helps!
See Ya
