Peter, I wondered if he was related. He has given me good advice in the past.
Hopefully he will have read this thread and respond.
Yes, I have grease nipples in the king pins (2) and also in the top & bottom pivots. The ball-joints on the steering arms do not have g/nipples but the rubber boot is able to be eased back to enable grease to be forced in which, if regularly attended to, should siffice?
Again, thanks for the advice and any further thoughts will anyways be welcome.

Glenn the grease nipples I speak of in the steering arms enable grease to find its way down to the outer ball joints and up to the rack to lubricate the inner ball joints under the gaiters. I fitted them half way up the shaft and pointing forward for easy of access. All Geoffs ideas.

I envy you . It seems odd to me that Bristol moved away from grease filler points for the moving joints. On my 408 it seems there's only grease nipples for the rear hubs. Everything else, it seems, needs disassembly.

Grease nipple conversion going well.
I found that I gave some false information in an earlier post.
The threads in the inner wish-bone pivots is 3/8 24 UNF. The grease nipples that I have, some old ones, some new are 1/8 28 BSP. Just thought I'd correct that fake news!

One-Shot to grease nipple conversion.
Before pumping Castrol Spherol semi-fluid grease with little added sae 140 (to thin it a bit) into the rack, I decided to try to assess any ‘stiffness’ this more viscous lubrication might produce. I looped a loop of string around a spoke of the steering wheel and attached an expansion spring to it. I pulled the spring until the wheel turned and noted how much the spring had stretched. Before I changed the lubrication, the spring stretched to 110mm before the wheel moved. I repeated this several times and got the same result each time – 110mm. I then took all of the One-shot system out of the car and let any oil drain from all the connections. After adding the grease nipples and the s/fluid & 140 mix I repeated the wheel movement test. Every time I repeated the test, the wheel moved when the spring stretched to 75mm. So much for making it stiffer, though I can understand the reasoning.
