Hook style plug set - What spark plug?
 

I recently purchased a plug wire kit, and it has the early style hook ends which is not what I was expecting. However, I actually like the look and want to use it on my C59A, as I'll also be using a helmet dizzy. I'm guessing that it will not fit on my Autolite 216s. Do I need plugs with a removeable terminal nut to use with the hook style plug wires? If so, does anyone have a recommendation that is equivalent to the 216?

These are what you need for the hook type wires > https://www.ebay.com/itm/NEW-1932-36...-/351249747296

Ok. So I need a plug with a removable nut. The NGK 6BL (3212) is equivalent to the Autolite 216, and it has a removeable nut. I'm guessing it has a M4 thread vs the 8/32" listed on the eBay site above.

Seems Monarch-Supply has some very nice nuts and "cooling fins" in both metric and imperial theads. Beautiful, but spendy.

So much detective work for this flathead youngin. Lol...

We sell the same nuts posted above with the red background with a m4 size

Excellent. I saw you had many items for sale on eBay, but did't notice the M4 nuts.

Here they are, however they would be a bit cheaper on a phone order...

Went back to NAPA where I had purchased the Autolite 216s, and they had one NGK 6BL in stock. The rest should be in tomorrow and I can return the Autolites. I'm really surprised at how well the small removable nut secures the hook. It will not budge. A comparison shot of the two plugs and the hook installed on the NGK. Now that looks nostalgic to me. Just need those brass nut now.
