Thanks TurboMan!
You're right, my spine was in agony and I broke the journey for a night in a hotel!
Underneath is very good apparently, with just one small weld needed in the battery compartment. Need to get it blasted underneath and am considering waxoyl thereafter, but struggling to find a recommended garage in the central belt to do it - I don't have the suitable space to do it myself (or the time to be honest).
Have had all the fluids replaced and a new battery as the old one was draining very fast and I was bored of jumping it already. Also new choke as the old one was snapped, as well as other sundry bits and bobs and it's running well.
Window seals need replacing all round and just been researching that and need to friend a willing friend to help especially with windscreen due to weight of it.
So far, loving it!
Cheers
Ben
