Hi Bob, sorry I've not got round to replying yet, I've been a little sidetracked trying to get the plasma cutter running with the new torch. It was a doddle to fit but it still doesn't work, I cant get the HF pilot to fire and as I need to get the shell cut up and weighed in to recover some cash for the mig I've had to resort to the angry grinders
I've not taken a measurement of the auto box from centre flywheel to bottom of bell housing yet but you were spot on with the flywheel which is 13 1/8". Also from centre flywheel to bottom of oil pickup is 8"

which means prob + 1" ish for sump clearance, might get away with it if I put tractor wheels on! so have resigned myself that a dry sump is the only feasible option.
I wasn't keen at first partly due to cost and partly because although I new what a dry sump system was I wasn't too familiar with them. I feel better about it now as I've managed to find some useful info about them and I don't see any reason that with enough time, more research and practice with the tig I couldn't do my own sump and possibly even the tank, with regards to a pump I think for my needs a 3 stage would be more than enough, 2 scavenge, 1 pressure. The M60 already has an external filter housing so should lend itself quite nicely, although as the feed/exit pass through the current sump I'd have to look at a suitable oil entry.
I've seen that link you put up in my searches, very sweet looking sumps

but no prices!
I found another dedicated kit, in the states again, but at just under $4k for the kit and sump its waaaaaay out my league:

Its going to have to be research, research, more research, DIY & Fleebay
When I get a few spare mins I'l get the crane out again and try the lump in the frame with no sump/alternator and see how it looks, and I'l post the piccies up.
