Power steering conversion linkage
Good afternoon,
I bought a 71 f100 this weekend to convert my truck over to PS with. I've read the article on the power steering conversion, but I have a question. Since I'm getting the PS out of the same model, can I just swap in the box and pitman arm, and not have to pull the drag link and such?
I know I'd have to with a 73+, but I couldn't find a different part number for MS vs PS in the parts catalog on those parts.
Thanks!

You can swap the box and pitman arm with no problem. Although the disc brake steering links are different from drum brake links, the pitman arm connection is the same. But the pitman arms are different and not interchangeable. The problem is with the column length. The power steering column is shorter to allow for the larger power steering box. You need either a power steering column, or you can shorten your manual column to fit. The difference is about 2.5".

The draglink with or without P/S is the same 1965/70 F100/250 2WD and 1971 F100/250 2WD before serial number M00,001.
1971 F100 2WD's from serial number M00,001 (last 6 digits of the VIN) and 1972 F100 2WD's use a different draglink, left tie rod and right tie rod end.
The P/S Pitman Arm is different than with M/S and 1971 F100 2WD's used two different P/S Pitman Arms:
C9TZ-3590-C (marked: C9TA-3590-E) = 1969/70 F100 2WD & 1971 F100 2WD before serial number M00,001 and...
D2TZ-3590-B (marked: D2TA-3590-BA) = 1971 F100 2WD from serial number M00,001 and 1972/79 F100 2WD & 1975/79 F150 2WD

No such thing as disc brake steering linkage and the OP isn't swapping in disc brakes.
I beg to differ. If you swap in later disc brake spindles, the center link and tie rods are indeed different. Therefore "disc brake steering links". I realize the OP is not doing that swap. I just added that for info. Although I don't have access to all the part numbers, everything I stated is true. Been there. Done that.

The Pitman Arm, left tie rod and right tie rod end used on 1971 F100 2WD's from serial number M00,001 are the same thru 1979, also the same as 1975/79 F150 2WD
The 1973/79 F100 2WD & 1975/79 F150 2WD draglink is different.

I do have access to all the part numbers. I've been looking these part numbers up in parts catalogs since these trucks were brand new.

Check the part numbers again. They can't be the same for two different parts. Left outer tie rod and right tie rod or center link, whichever you want to call it.

I have a '70 that I'm wanting to convert to power steering as well. If I don't want to go to disc brakes, can I get the box and linkage out of a dentside and have it bolt up to the original drum brake spindles?

Only 1973/75 F100/250 4WD's came with front drum brakes.
Front disc brakes introduced in 1973 F100/250 2WD & F350 (1975 F150 2WD) as standard equipment. As standard equipment in F100/250 4WD in 1976.
Front disc brakes were optional in 1968/72 F250 2WD & F350.

If you're not changing to discs, you can simply swap the steering box and pitman arm, along with the steering column. The PS column is shorter than the manual column. The column can be shortened, but I haven't done that.
