get down to partco or something like that m8, they're all good enough for the job.
one thing to look out for is those fcukin little metal spacers (that keep the gasket from over tightening) i went round the sump and the bottom end but still managed to miss 1. when i tightened it up crack. made a wee crack in the sump along the hole.got it fixed with a bit of metallik fae halfords.
you have to take the oil pick up pipe off aswell. you shouldn't need anything more than a ratchet/small extension bar and a 10mm socket, oh and a scraper with some hylomar (gasket sealer).
doesnt take long, took me an hour to do and thats with fixing the sump.
