HEY, GUYS. ONE LITTLE THING MAY BE OF INTEREST. A TR7 RACK CAN BE ADAPTED TO A
SPIT AND IS SHORTER THEREBY REDUCING THE BUMPSTEER WHICH, ON THE SPIT IS
HORRENDOUS. RATIOS, MAYBE BETTER? CHEERS, ED..

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.... ;-)
