I had no luck through my local Volvo dealer. $100ish for a genuine one, and they ordered in the wrong thing for me three times before I cracked the poops and bought one from UK ebay for ~$20...
I didn’t need a bearing, so cannot offer any help there.
Gearbox drain and/or fill plugs are something weird like 10mm square - a 3/8” socket drive doesn’t work. I ended up using a 10mm allen key with two corners filed down.
Radiator hoses are the same for all NA x40s, IIRC. The bottom one might even be the same as a turbo x40? I have good used ones if that’s any help?
