Hello, was wondering if anyone out there has the casting# of the power steering pitman arm for a 1966 chevelle.I'm converting from manual to a JGC box.I think I kept the p/s gearbox off of a 67 malibu years ago but would like to make sure the pitman arm it is going to be the right one.Ya know how the memory starts fading over the years! Thanks

Mine is a bit hard to read, looks like;

GMC15

Just pulled it off this evening... looks dirty, but this will give you an idea of what the correct one looks like...

Thanks for the pics Roger! I took off the pitman arm on the unit in question and it has a casting#5693764B and looks like the one you have pictured.
