Yeah, the book oversimplifies everything. Thanks for the insights... both of you.
Phak... what is the measurement between the pins? Listed as "to fit" but yours fit yours then it should fit mine also. Do you happen to know offhand that measurement? Would save an old man a lot of neck-crinking and larger bifocals.
Bill... I have a Proto 1/2" drive screwdriver socket that fits the slot. Should work.
Thanks, Y'all.
Jethro.
