THOR is working on a '74 so the power and manual steering pitman arms are definitely different. The '73 and later cars have large sector shaft power steering boxes and small sector shaft manual steering boxes so they use different pitman arms. The '72 and earlier cars have small sector power steering boxes which use the same pitman arm as the manual boxes. The only large sector manual steering boxes extant in Chryslerdom came in C-bodies and B-series vans.

My '72 B300 was originally manual steering which I replaced with power steering from a '78 Dodge Magnum.

Okay, thanks to all of you for your input
For now, I'll probably just keep power steering in my Volare. I already have a FirmFeel steering gear, so I just need to find out exactly where the leak is coming from. My first guess is the pump itself, next guess is one of the hoses.
Thanks again for the input, and I agree that safety is important!

Right, thanks, totally spaced the small/big spline split after '72.

Too many people who were born on third base actually believe they've hit a triple.

Okay, I took my manual steering box to an O'Reilly Auto Part. I ordered a pitman arm just so I could compare it to the pitman arm on my manual box. The arms look identical. The pitman arm on my power steering box looks just like them also.
So, I may splurge for an adapter when I get some extra cashola.

I'm not sure when that will be though...
