WHAT IS THE CORRECT CASTING # FOR A PITMAN ARM ON A 1969 CAMARO QUICK RATIO P/S BOX THANKS

[Big Block Bill]

I believe the casting # ends in 227

Fast Ratio Pitman 3958227 BGMT5
That's the number off my 04C L78 Z11

What else do you need?

SO WAS THE MANUAL & POWER STEERING PITMAN ARM THE SAME NUMBER I HAVE SEEN CASTING #3953227 ARMS BUT THEY ALL SAY FOR MANUAL STEERING

Mine was a PS car with F41 suspension
I will have to check a Manual box/pitman arm I have marked from a Z years ago

From CRG (http://www.camaros.org/suspen.shtml#steer)
"Note that the same pitman arm forgings were used for both manual and power steering, but the splined holes for the attachment to the steering box were different sizes."

IS IT A SPLINE COUNT OR A SIZE IF SO WHAT IS THE SIZE I WOULD BE LOOKING FOR ? THANKS

[ZLP955]

Not sure, never had one of each side by side to compare difference. My car has the manual steering box but I haven't pulled the pitman arm yet.
I have an idea that the output shaft on a PS box is a larger diameter than on the manual version (in the same was as the drag link is a larger diameter with PS), but hopefully someone else can confirm and answer your Q.

Further to previous post, just looked at a manual box that has a 227 pitman on it, and the arm has a 'M' stamped on it near the splined hole. Wonder if they have 'M' or 'P' to denote application?
