Just to complete my dialogue on dealing with DJ remotely.
Martin (UK distributor) reckons they have had a lot of 'retirements' recently and may not have invested early enough in training people to make stuff so they are short handed. He has experienced long delays but things are still getting made by the experienced hands.
I may change my harness as a result - I needed it to set things up (invaluable advice as always from youse guys); Cinched up it seriously altered my arm reach and therefore steering wheel location. The lower hip adjusters are right on the bone so I was going to get those altered but maybe I will wait and get something from scratch to spec (now I know what spec is) closer to the time. Maybe DJ will be in full swing again by then.
