I dont believe that the Autolite AR-5's are available any longer.
The plugs in the car (stock 6 cyl 201,3 ci) now are Champion J19LM - I have an old Champion catalogue that specifies RJ12C - so the 19's are likely too hot although they look OK and the car runs well.
Can you recommend the correct plugs? Champion or NGK would be great but other recommendations appreciated.
Many thanks

I use Champion J-8 or J-11 in my '36 P-2 (201 cubic inch engine).

AC 45 or 46 if you need a bit hotter plug. I find them to be easier starting and better running than the Cahmpions.
I have a box of Autolite A-5's if you are interested. 10 plugs in the original box.
I believe the "R" designation stands for "resistor".
Maybe you can use them. Just let me know.
