CORRECTION-
SR2 (not LS2)
I have a 1971 Lister SR2 with a 6.5kW in-line generator. I am exploring how best to replace the generator with an alternator and looking for advice on where to start. I've seen belt-driven set-ups. Are there any in-line set-ups? The Lister is deep inside Canada and hard to get to so I need as much of a bolt-on setup as possible. Any guidance or opinions would be appreciated.
I answered my own question-

Has bolt-on solutions and is very helpful.
I run a ST5 on a belt drive at 1400 rpm, but you could easily run a ST5 or ST7.5 on direct drive @1800 . I think Georgia Generator has single bearing flexplate units that will bolt up to make a more compact package.
