Holden and H.E.I make those types of dizzys, and can be built to specs using the same parts and caps for different name cars....its how they save $$
the internals are the only things different..
All this is good info,
I usually use a rubberized heat shrink tape that electricians use on an underground cable's joints but over the years it gets hard as a rock and sometimes crispy if heated continually.... so I'm still learning...
