For a stock distributor you need a flat head screwdriver to adjust the points mount and a 1/8" allen wrench to adjust the dwell. You also need a dwell meter (set to about 30º) unless you want to use a points gap gauge (set to .019"). All of these tools are available at almost any parts store.
I never knew such a thing existed. Is there any advantage over a regular little L-shaped allen wrench?
There's lots of stuff out there that only the professionals know about. Did you know that there are extra long screw drivers...about 4 feet long for adjusting the idle mixture and idle speed? I've got a pair that I've loaned out to a friend which really help on hot days when it's too painful to lean over a hot engine...I'd rather get my tan the old fashion way.
