I agree with your approach using our real advantage as time rich private restorers. So what if takes hours - getting an unstressed connection at the ports that you don’t have to worry about will be worth it. Too much to hope that these aftermarket units would just bolt on but your patience is going to be rewarded.
Oh David I like the term
time rich I just wish I had the phrase
energy rich to match it.
I fitted the side stand in place before fitting the left side system - when using my spring puller I was giving it more grunt that some well known Tennis players.
It was my third full on fully grunted effort that got the piddling looking spring into the slot! :'( :'( :'(
