biggie.......dunno where yer comming from. Yeah the 4-nipple squarecan dizzy kenn gitt confuzing. The points (0.015) are designed to be replaced on the kitchen table. (seriously) just un-snapple the capple and walk. Installation is a reversal of the removal ...except... finger start the 2-bolts and putt-onn the rotor. Rotate the rotor until the OFF-SET tang fit the OFF-SET drive slot and now tighten the 2-bolts. 'cuz ittza OFF-SET drive scheme, ya kent gitter outta time. Now re-snapple yer capple. Simple, eh? OH yeah, remember to stick the corner of $1-bill (cheap) between the points (0.015) and PULL. Polish the INVISIBLE CORROSION from between the points........HTH, Dell, yer self-appointed sparkie-meister

This site sells a terminal kit with a spark plug looking terminal threaded on one end . #1247XTTERM for $17.49

Or you can soldier one end of a copper core plug wire to the top side of the terminal inside the hollow coil .

Keep in mind that the square coil is held on with a bail and anything sticking up on the front half of the coil will be in the way of fastening the bail wire .

I fabricated a terminal that pointed out of the front of the square coil . After building and installing I found it cleared the fan blade by only 1/8 inch .

Bigbleeker,This is what I have done first one about 30 years ago,many since, if you have your coil cleaned out(the hard part),why don't you just solider a length of copper core plug wire to the front terminal inside the coil.Then drill a hole in the top side of it to the rear of the bail to run the coil wire to the round coil, secure the coil wire with a wire tie inside around the wire so it dosen't pull out of the hole and seal it up with some silicone.Also solider a wire inside to the the pig tail connection and drill a small hole to run it out of the square coil to hook to the points side of the round coil. A good conversion,you'll be glad you did it.

solider a wire inside to the the pig tail connection and drill a small hole to run it out of the square coil to hook to the points side of the round coil.I made a mistake, I soliderd a wire short wire inside to the the pig tail connection and to the top lug post inside of the coil top for connection to the coil.

I see others install behind bail wire next to stud in back of coil.i will order the spark plug adapter from here.

Heres mine, I drilled a hole in the square coil and took the tower off the round coil and just ground it down on the bend top belt sand until it fit. A little epoxy filled in the rest.

I did a similar conversion about 30 years ago too, Last year the machine started running a bit odd. Seemed like spark so I thought I should check the coil, opened it up and found 1/2' of water sloshing around inside. Drained it and all is well. I figure I should make a note on the calendar to check it in another 29 years, before it can become a problem.
