Steering Column, part 2

I've been suffering from a severe case of the man-flu for the past week so haven't done much on the build...
I managed to brave a few hours in the garage today though and have (possibly) finalised my steering design.
After lots of playing around I've decided to keep it much the same as my first attempt, but have managed to drop the height of the steering wheel by an inch or so.  Ideally I would have liked it another inch or so lower (and possibly a couple of inches futher forward) but I can't easily acheive that without cutting a big hole in TR9, or making the steering linkages go through a rather tortuous path.
So basically all I've done is get rid of the gap I had previously left between TR9 and the column, so the column just touches it.
I did that by cutting off the top rail of the column support SW2 and replacing it with another tube a little lower.
I guess I could have just added a spacer, but it wasn't level anyway which would have forever bugged me if I had left it as it was!
Whilst I was at it I also added a little plate to TR9 with two holes in it so I can use a 38mm exhaust clamp to add a little more support for the column:


I've been wondering for a while how to link the mazda column to the escort rack and had a bit of a brainwave this weekend.  It's possibly a silly idea, and a waste of a perfectly good sierra column, but...
I started off with the MX5 steering rack linkage, which I cut down on one end:

I then dug out a Sierra colmn I had lying around, chopped it in half and mated the two together:


The Mazda end mates with the lower part of the MX5 column, and the Ford end mates with the steering rack using one of RallyDesign's Sierra-to-escort linkages:
