Yes, the JW kit is a good and easy option but still leaves the bottom bearing which gets ignored. Considering the angle of the universal joint below this bearing I would think the angular loads are greater at the bottom than the top. Although the top is normally the spot where the MOT will focus on.
All this is probably fairly trivial but nice to get a good engineering solution. Since I have the facilities/time and the web makes it easy to size up suitable bearings I'll soldier on with this project for the moment.
I'd like to know which car the Factory nicked these columns from as the bearings don't appear in any catalogue I have found.
Once I've worked out how to upload I'll post some pics.
