I was thinking more along the lines of XK120s and E-Types when they still had “carburettors.”
Yes, British electrics are a nightmare.
I read somewhere that you can cure the anemic charging system in MGBs by using an alternator for a Chevette. It may be blasphemous, but if it works, so what? Just keep the original parts in a box and go driving.
Once saw a chap wearing a t-shirt with the Lucas logo that read, “ If Lucas made guns wars wouldn’t start”.
Having known several folks who owned MG’s of varying vintages I found that to be quite amusing. And true.
