This article covers the steering column, steering shafts and rack and the steering wheel.
The first thing to do was to drill a hole in the bulkhead for the column. Drilled the hole just a tad bigger than the diameter of the column shaft, slotted it in and temporarily bolted it in place. For securing, there are two dashboard cross-member fixing points and a chassis mounting bracket which holds a regular exhaust bracket which clamps around the column shaft.
The top steering shaft is supported by a heavy duty rose joint, rod end, i.e., the type with the self-aligning bearing; and the lower shaft slots into the steering rack. All this is held together by three stock UJ's.
Dry fitted everything together, not forgetting that each UJ needed to be mounted [on the shafts] with subsequent spline bolts 90º out of phase with each adjacent UJ. No idea why, but that's what it is. Also, each shaft-end needed the groove filing a bit to accommodate the bolt. This to provide an extra [physical] locking mechanism for the splined shaft. However, at this early stage, I'm just going to use smaller bolts to get all the measurements and angles right. Then, when I'm ready to fit-for-good, I'll adjust the groove depth to accommodate the proper bolt size.
Assembly was straightforward, but I did have to cut about 1 cm off one end of the lower shaft as it was too long. This is normal procedure for the GD Euro as the shafts are stock... So far so good.
Disassembled everything [again] and drilled out the bulkhead to accommodate the steering shaft rubber gaiter. I also had to repaint the lower end of the steering column casing as I scratched it many times when trial fitting and doing all the other stuff.
Not having the dashboard or seats fixed in place yet I positioned the column as far forward as possible (there's ~2-3 cm to play with); and this consideration needs to be factored into the rose height and its adjustment range i.e. if I have the steering wheel further away from the dash' the top shaft would have to be a bit lower. There is plenty of height adjustment room on the rose-bearing, so when I get the seats and everything in place I'll adjust as necessary.
Turning Circle: When I've adjusted the shock absorbers and springs for ride height etc. I will have to put a turning-circle 'end-stop' inside the rubber gaiter of each arm of the steering rack. This to restrict the turn of the rack, therefore preventing the tyres from catching on the engine bay side wall during full lock... Once again, normal procedure but not ready to do this yet.
