AFAIK:

66-70 B-Body V8 K-Members will all interchange successfully
Whilst E-body, and 70-71 B Body K members will install on your car, the steering box will be mounted at the wrong angle


From what I read on the internet I suspect the larger spline pitman may require the later drag link and idler as well, but I have no actual personal experience of this.

<<67-72 manual and power boxes use the same pitman (small sector, early linkage)
73+ power steering (large sector, late linkage)
73+ manual (small sector, late linkage. This can also be used on a small sector power box to use a 73+ steering center link on an earlier car)

I'd be tempted to get a large-spline pitman from somewhere and see what it looks like. I believe the retaining nut and washer are larger as well.

I'll check my stuff later and see if I have one.

'72 up Challenger / Cuda has a different Pitman and nut to a '70 - '71 from memory.... and thus different to "B" Body.... agree on the box angle too but not really material....

Bananarama! it

I'm also running quick ratio aftermarket pitman arms.....

I shall order the correct power steering box....


I can see a for sale add coming up...

did you cut off your steering shaft? I can't see pictures at work.....

if not buy the kit from bergman auto you get the pot coupler and pipes in the kit.... no cutting no solid joint between box and steering shaft = long lived steering box bearings

Wasn't aware of the steering box angle difference between the early and later B/E K frame, handy to know.

Im not sure it is as the new box arrived and it's identical.

The only difference between a 1 1/4 box and 1 1/8 box aka (early / late) is the size of the output splines .. 1 1/4 and 1 1/8.

My review is good

The unit does what it says on the tin and really happy.

It’s lighter than I was expecting which is great as I love my PS


With no play I now feel I have more confidence to drive it quicker.

Great upgrade should have done it in the beginning

I cant believe you managed that 'in situ' ! Well done.
My rebuilt steering box is super light now but I wouldnt say the feel is any better. Good move i think.

whack in some more +castor front turn buckle thingo on both of you new fandangle upper arms 1/2 turn longer each

The box is identical, it's the K-Frame that's different - the tabs mount the box at a slightly different angle.....
