If your steering rack has the notched spline and not the groove all around i have used a 5/16" bolt which locks it in place so if the splines fail it will not slip.
Buy the best stock rack you can and use the plasic restrictors.
If in doubt, flat out. Colin Mc Rae MBE 1968-2007.

I may have a rack.
Getting hold of the splined part of the column is difficult, I don't think any of the big boys sell them.

It's almost certainly the bottom of the column that's gone rather than the pinion as the column is much softer metal. I had the same thing on Tubbs.
Tightening the pinch bolt does diddly if the clamp is already tight - you can heave on the spanner until you or the bolt ruptures, but you won't affect the clamping force. In all probability on strip down you'll find the clamp very tight but the splines stripped...
Racks are easier to buy and change than finding a decent column, but with Kreachers conversion that may not hold true !
If it is the rack, just get a brand new one and fit the MPi end stops if you need to.

Does anyone know from experience whether there's any difference between the Sportpack racks and the standard MkII+ racks, other than the reduced lock radius?

The left hand drive rack is about ten years old, same age as the VTEC conversion when we switched it out from right hand drive, but I've been noticing maybe a 1/4 inch play in the steering lately. And there was one other time probably 6-7 years back when I noticed the column pinch bolt was loose and cranked it down.
So without tearing it down, I'm thinking at minimum to replace the rack, and evaluate and possibly replace the column or weld on a new bottom splined clamp if it shows sings of being stripped out.
Any suggestions on the best rack to use? I have 13x6 inch wheels running the ubiquitous 175/50-13 A539 Yokos.
