Hi guys, I recently bought a 2004.5 sportsman 400 with some parts missing, and I was hopping you could help me identify what I need and where to get it the cheapest. I attached pictures below. I looks like I need the radiator guard and bumper support? Would radiator guard from a 2004 sportsman 600 work? I would like to mount a winch in the front too, preferably somewhere low, in case that changes the parts I will need. thanks.

I also need screws for the belt cover, those are missing too, do you know what size those are?

Thanks for your help.
