Update – Starter motor came out easily! Access makes it hard to fully remove. Is it possible to get it out without removing the manifold? Maybe by lowering it downward?
Engine seems to turn a bit now, I didn’t want to move it too much yet. Something sounds a bit like lose parts in the gearbox, hopefully nothing broke off, can’t be sure until fully remove the starter and check it. Gearbox turns freely and quietly if clutch is in.
Jacked up the wheels. Front two turn ok. Rear ones won’t budge. Is there an adjuster I can try to free them with before taking wheels off? I suspect the brake hoses are perished a bit. Not sure what state the pistons are in, likely not good, but I have only one spare piston.
