Power steering identification help

[Big Green Duster]

I have a 72 plymouth duster 225 slant six a/c with power steering. The pump makes noise and the power steering gearbox leaks can anyone help me identify what pump i have and power steering gear box. Or point me in the right direction to get a replacement or rebuild kit.

I know the cap is not original the original one went missing if anyone knows who makes reproduction ones that would be appreciated as well thanks

Just replaced my steering box. There are 2 different size boxes. The only difference is the pitman shaft diameter. 1 1/8 or 1 1/4. Sure envy how much room you have to get the thing out. I have 360 and 1 5/8 headers. It was NO fun.
