Time to seal up the cab floor around the steering column

Steering column painted and final assembly

Steering column redesigned with coupling inside the tube. Painted and ready for assembly

Steering column, some assembly before paint.

Made some guide lines and measurements to figure out where to drill the small side hole for the grease fitting. 

Got some Steering column parts from a friend

My design intent below and the manufactured bushing and lockring above.

Some steering column prep work

Distance between Cab floor and CPP 400 Power steering box top is 120 mm. Gear shift linkage need 90 mm, so the coupling needs to be mounted inside the column tube.

Steering column modifications, design stage.

I was inspired by a thread at FTE to try and make my own solution.

To combine the CPP 400 series power steering box and the stock steering column with manual shift .

As I dont have the cab mounted to the frame yet I didn´t know the distance between the end of the output shaft of the steering box and the floor of the cab, so I asked a friend of mine to take some measurements on his truck, and that turned out to be about 90mm or just above 3.5". The manual gear shift assembly at the end of the column is just about the same length 90mm or 3.5", then it seems that it will be quite tight, with the shifter arms to move freely. So I figure I need a little bit more room than 90 mm

Revision 1

The brown part is supposed to be a bronze bushing with 2 o-rings. The coupler is the flaming river FR1944. The sleeve outside the coupler and to the left of the bronze bushing is a lock ring that uses the existing set screws of the coupler. This is made to lock the steering shaft inside the column tube. The set screws is locked by a hex nut.

Steering column dissmantling

As i am planing on using a CPP power steering box and wants to keep the stock column with manual gera shift linkage I need to do some modifications. First of all I need to take everything appart.

Stock -56 steering column with manual shift linkage.
