They probably spot weld those clips when they manufacture the fender, so yeah I'd tell them I want a new fender too. The fender supports are all bolted. I would imagine you can loosen all the bolts and position the fender so that you have the proper clearance and then tighten things back down. Something that should have been done when they built it.

Where can I order a new rear hub ?

And sprocket with new bolts ?

Hopefully no one needs a new hub,JD630. the new sprockets are not as thick as original.these photos kind of show that.

i had to make a shim so that mine would not wiggle around. you may only need to shim up what you have. new sprocket and bolts would be better first.

here is what you should have to put on a new sprocket. the 2 top rings are original parts, the bottom is a shim i made. whatever you buy determines the thickness of the shim you need. i bought a shim washer, made the middle bigger and slotted the outside for the nuts with a dremel.

when you take off the wheel, you only need to lift the entire sprocket configuration out of the hub. you do not have to loosen the nuts first to
take it off. the whole thing will slide right out. so never mind the new
hub first. park it first and rip it down. if you can get a spacer in there,
that may be all you need. but do it now.! good luck. dont give up.
just do what the other guy who sold it to you didnt do.
congrats on df250rtb ownership. the bike is the balls.
