Pitman Arm - Plan B

[PA Dodger]

I went to put a new pitman arm on my '69 Charger today and it looks like it may be the wrong size. I ordered the correct arm for the car. I'm thinking I got a large spline power steering box when I exchanged the old one for a rebuilt. So what are my options now? A new '73 and up arm? Is there a large spline swap arm for a '69?

I'm going to assume your new gear has an 1.250" pitman shaft. If that's the case, you can surely use a '73/up B-body pitman arm. Since the '72/older 1.125" gears are so hard to come by, it is commonplace for auto parts stores to do the 'switch-a-roo'!

Birdflu - I wasn't sure if the '73 and up arm had the correct shape. Also, I kept running into info stating that the large spline boxes were used in vans. I was hoping for easy but knowing how mopar stuff goes was expecting some sort of one-off. I did find someone selling early b body arms forged with the large spline. Very expensive.
