Absolutely gutted. The rockershaft is for something else, possibly a b series. It's about 3 inches too long and also too large in diameter. This really put a damper on progress. I would have got it going today otherwise.

Went though my parts bins and picked out all theissing nuts and bolts and nuts and pieces

Fished up a spare starter that I put new brushes in years ago and never got working right. Will play with that in the morning and sort it out, a dodgy connection I think. Can Rob the generator from my 1300 as I'm putting an alternator on that. Then it's just missing a distributor cap, rotor, plugs and leads. Will retap the water pump bypass to the head in 3/8bsp as it's normally a unified special thread and not easy to get a tap and die in. Can buy a new fitting, but for a couple of dollars I can put a decent brass one on (or easily block it off as most people recommend).
Missing a disc in the oil filter unit, I wonder if it was run like that for a while, plenty of sludge in the tappet gallery, without the disk the oil bypasses the filter.
Then some seals for the rocker.cover bolts and the tappet cover bolts.

I think I will have less than $100 in it so hopefully I can get a little bit back for parts for my 1300
