OP has a 1969 F100 2WD
C9UZ-3A525-A (replaced C9TZ-3A525-B & D3TZ-3A525-A) .. Steering Coupler (aka rag joint) / Obsolete
1969/74 F100/250 2WD & F350 with M/S & P/S; 1975 F100/250 2WD & F350 with M/S only.
No Ford dealer or obsolete parts vendor has any NOS
Dorman Products sold by auto parts stores has a replacement.
The rubber piece is available from auto parts stores, but it's a real b!tch to install.

It makes no difference with Bendix or Ford/Saginaw P/S or Manual Steering.
There's only one steering coupler for 1969/74 F100/250 2WD & F350 with M/S & P/S; 1975 F100/250 2WD & F350 with M/S only.
It doesn't look anything like the replacement coupling in the pic.
Bendix P/S: 1966/68 F100/250 2WD; 1969 F100/250 2WD before serial number D96,001.
Ford/Saginaw P/S: 1969 F100/250 2WD & F350 from serial number D96,001; 1970/79 F100/250 2WD & F350.

Spline on the shaft coming out of the steering gearbox is 3/4"-36 spline. The end of your steering column shaft doesn't look the same as the end of my ('78 tilt wheel column) shaft. On mine, that end is also 3/4"-36 spline. Looks like you have a double-D setup.
I have a Borgeson stainless steel 3/4"-36 x 3/4"-36 steering joint on my truck (no rag joint).
View from under the truck when I was installing the steering joint and the column.

I have found them on E-bay, you just have to be diligent and set a search alert for the item you're looking for or check on a regular basis. The OEM Ford design is beneficial in that it has some vibration isolation qualities and also minimizes any column misalignment issues.

Well after inquiring with the vendor I purchased steering column from I actually need to install a 3/4 solid D shape shaft inside the DD tube and then attach the U-Joint to it. I found an example photo, live and learn !

There isn't a steering coupler (rag joint) with 4WD .. These trucks have a multi-piece lower steering shaft & coupler assy. that also contains a replaceable u-joint.
1966 F100 4WD; 1967/75 F100/250 4WD: The lower steering shaft and coupler assy. connects to the input shaft of the steering gearbox w/a clamp and pinch bolt.
