I would just use the same wheels as on the 4 1/4" its not going to make alot of difference, could probably get the smaller guard off eBay anyway.

5" angle grinders are often 4.5" angle grinders with a larger guard, and a more powerful motor. Housings, arbors, flanges, and sometimes even the gear set are the same.
Much like how a while ago, 4" grinders were often homeowner grade and 4.5" was the professional level size. Now almost every cheap angle grinder is a 4.5" and power tool companies are selling ultra powerful (but still compact) 5" angle grinders.
4.5" attachments should be perfectly fine in a 5" angle grinder.
Lots of places do sell 5" attachments. The choices aren't as expansive as 4.5", but they do exist. Lehigh valley abrasives is one that has dirt cheap attachments for the 5" size. However, for flap discs and grinding discs, the extra 0.5" increase in size often has a much larger cost increase. For flap discs, I run 4.5" (which are like $3 a piece, compared to the $4 for the 5" flap discs). It's not worth an extra dollar (33% cost increase) for an extra 0.25" of reach for grinding.
For cut off discs (where the extra size really makes a difference) I do buy the 5" cut off discs. For the cut off discs, it's only a few cents difference between the 4.5" and 5", making it a much better deal. The extra 0.25" reach for the cut off discs is almost always useful, and it comes a such a small cost increase. The Metabo Long life super slicer 4.5" are $1.09 each, and the 5" long life super slicers are $1.19. $0.10 increase in cost is worth it for the slightly longer cut depth/reach and slightly longer life.
