I just pulled the steering box out the black buggy to see why the new 36 spline universal or the other VW universal I have will not fit on it. The dimension I took off the splined end of the steering shaft mount was something like 0.64 and the spline count is high. I quit counting at 48 splines and I was about 3/4 the way around the shaft.
On the box I see the VW with an "F" off-set to the right and just below the VW symbol.
At the bottom I see what looks to be either a raised * or a + with a raised SF in-between the two symbols: *SF* or +SF+
In between the VW and the SF is a raised area like you might have for a P/N. I can't make out what is to the left on this area (faces the opposite way/upside down than the rest of the markings) but in the center there looks to be a raised #11, a space then a raised #64. I am assuming the 64 might be the spline count but that is only a guess.
Any ideas what I have and where it comes from?

This is a duplicate of my build string on the off-road forum. Below are added pictures.

The number on top is 7b.

This is by the shaft going to the Pittman Arm. The number might be a 14.

The next three pictures are of the main body of the steering box. The arrow points to what I think it the number 64.

This was shot with no flash and I pushed the editing of the photo a bit more than normal.
The number at the bottom seems to be a 1.

A similar photo but with a flash then pushed during editing.
Can anyone tell me what I have please.
Thanks Lee
