I'm with you alls .
Born & raised a Yankee farm boy means you learn how to squeeze the last bit of use out of anything .
I've been a German car mechanic for most of my carreer , these cars are great as you can take them farther apart than you can get the needed parts...
Most Bosch distributors from the points days have this same tiny screw & washer syndrome , I learned it the hard way when I was 14 or so
Those who own W-123 based mercedes know they'll never wear out , only get rusty or wrecked .
BTW : borrowing a timing light with the advanvce dial allows you to use the
" OT " mark (TDC) and set the full advance to 32 ~ 34° all in and that old 6 banger wil REALLY scream ! .
Points go to 33° dwell for the best coil saturation and hotter spark .
