After the last 50 or 60 years, who knows. From the factory, 3/8" reach spark plugs were used on all WD45's and early D-17's prior to chassis s/n 24001. Any D-17 after that and all 170-175's were always 3/4" reach plugs. HOWEVER, if you replaced a tall cylinder head with a new one from A-C, you were given the newest head, which meant 3/4" reach plugs. So, one must look over the depth of the threads if there's a question.

It's the stock head, I was told it should have non resistor plugs. I don't even know if that is correct.

With a mag you don't want resister type plugs.

I thought the older short cylinder heads on the WD's took 3/8 reach plugs and the taller heads on the WD45 and D17's took 3/4 reach plugs.

I run NGK3112 in my WD45 and have had very good luck with them so they should be fine in your WD

Today's Featured Article - The Fordson F Ignition System - by Anthony West. A fellow restorer contacted me earlier this year asking for some help and advice on a model F that he was restoring. He had over a period of months spent a fair amount of his hard earned cash on replacement parts for the old "trembler" ignition. Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!!
