JJW, I may be paraphrasing a bit here but from Mulfab it was essentialy do the shortened rebound spring on a race car (maybe) but not really worth the call on a road car. That's my recollection of that part of the conversation and I do apologise if I am misquoting. It would appear there are many respected authorities on this, each holding different views.
The purist in me agrees with not doing KP's without the bushes, the pragmatist says think it through before throwing the idea away. It all comes back to the state of the bushes in every way and as they seem (strangely) to be more hardy than the KP's there seems little point in creating scrap and work for the sake of it. But I haven't seen or inspected mine yet so I don't even have an opinion, let alone any data on which to act. It just seems an idea to be worthy of thought. I have access to an aerospace metrology unit where bores are measured to far greater accuracy than we require for our KP bushes. I think a little measurement might come in handy here when I have the stubs off the car.
I'm also advised no one has yet had to replace Hardened Chrome KP's because of wear - just the opposite to the mild steel factory efforts: unless of course anyone knows differently in which case the mileages would be interesting.
As you say - many variables. You're never stuck for something to think about when you own a Morgan.
