I've only ever seen one mounted in the flesh David and then on a Mk2. My original restorer has one in his collection unmounted.

Yes, maybe. I'm not an expert on these things.

One thing that does occur to me is that the dynamo-driven pumps got more powerful as time went on:
Early Mk2: 800 - 850psi
S-type: 1,000 psi

So, if instead of rebuilding the PAS pump that was original to your car, as you were planning, you were able to source an earlier Mk2 pump of lower pressure, you could achieve reduced assistance. Or ICS or similar may be able to put some sort of restrictor in to reduce the pressure of the 1,000 psi pumps.

Although my car wanders about a little at speed, I don't find the steering overly light, but it is a very personal thing. Mine is a 1,000 psi pump from a Mk 10.

If anyone wants a smaller wheel (13inch) I have a vintage Les Leston wood rim wheel - no boss up for grabs.

This is something I have always wondered about for those that don't like things too light. The PS Pump includes a flow control/pressure release valve. Is it possible to adjust pump output pressure using or changing this?

I have the 15" riveted Moto Lita only because I could not close the door with the 17" wheel and my knee in the way. Plus, I cannot go any smaller since I do not have power steering. I guess I better not get any bigger. 6'4" and 290#.
