============
Walt, I'm confused here. Physically, TR and Spitfire racks are about the same 
externally, although I can't vouch for the angle of the pinion shaft as it 
connects to the steering column. But they're about the same length or width or 
however one wants to describe that measurement.

Meanwhile, the Spitfire rack is something like 3.75 turns lock to lock (GT6 is 
a bit over 4 turns). The early TR4 steering rack, which as I recall also 
mounted solidly as opposed to the rubber bushings used on later TRs), was also 
2.5 turns lock to lock, so I've long wondered if this "new" quick-ratio box is 
much more than a "replica" of the original TR4 rack.

I have an early TR4 rack that I've been saving to toss into the autocross 
Spitfire 4 (assuming that I -- or my daughter and/or son -- ever actually dig 
it out and start autocrossing again). I've also got some early Herald steering 
rack mounts, which were "solid" as opposed to the later rubber-bushed mounts. 
Or maybe I'll just toss all this good stuff, and the Spit's motor, into a 
street Herald.... ;-)
