[ABento]

I have checked at napa and have not found an adapter for the 18 MM plugs such as John Deere or International use, and I believe that the "A" plug is 7/8 x 18 not 18 MM, I asked here about an adapter and Branten sells them for 6.50

It seems I missed the post by Ford fixer, I was under the impression that the 7/8 x 18 was not in MM.
