SB K-memb Decode!?

[DEVIOUSDUSTER]

Hey all,

I'm a little confused here. I have a 70' Duster and am redoing the bushings and converting the steering from power to manual but have run into a road block.

The K-member in the car has front disc brakes, which is making wonder if it's a later K-member.

I have the manual steering pump but the idler arm seems to be different. (I know there are two different orientations for 67-72 then 73 and up) but i'm not sure which I have.

I have the number (905M441) off the K-member casting. Can anyone tell me what I have?

If it has spool moter mounts it is newer, 73 to 76

The pitman/idler are specific to the centerlink used.

67-72 enter from the bottom, pointing up.
73+ from the top pointing down.

The K frame has no bearing on this if it's only that piece. You can mix the 67-72 steering gear with a 73+ K frame and vice-versa.

67-72 are the biscuit motor mounts and 73+ is a spool style as mentioned.
