the alernator should be easy to do, take it off, take it to a auto electrician, get them to stip it down take the cage off have the cage chromed and have them rebuilt, they shouldnt charge you anymore than 40quid, as thats what they charge to re-furbish one, which means they have to strip it down first, and re-build it,
little things like that make the difference, im tempted to have all my bits chromed instead of polished, i would also get the bonnet catch done, inlet mani bracket, (around the dipstick)
