This is all I have on the field mod kits, I only found it recently and I haven't quite figured it out. Also it applies to a very early type of steering gear which I didn't even know existed. However they appear to be the same mods I've been talking about - steering height, driver's seat height, and the shim under the steering box. Clearly there was a problem for drivers, because two of the kits address those areas specifically. The other two kits are conversion kits to the later type steering gear, which is what we're dealing with now. Presumably this was an improvement for most drivers, but not enough for tall drivers.
Anyway, as I said earlier, it proves we don't have to accept Cab 11/12 problems as a fact of life. These kits would not have been designed and issued if they didn't work, and there's no reason we can't design a kit for the later type steering gear.
