Circular saw arbor shim?

[Legion Prime]

So I've found an old SkilSaw 534 in the garage. It being bladeless I grabbed a 6.5" Plywood/OSB blade for it while out and about. I get home to find out the blade is made to fit a 5/8" arbor but the saw has a 1/2" arbor. Looking around online the vast majority of blades made for 1/2" arbors are 4" with the occasional 6" thrown in.
I have however found shims. Now, do I drop ~$10 on a 1/2 to 5/8 shim that I apparently fit into the blade before mounting the blade in the saw or, having seen some blades that have a knockout to convert the 5/8 arbor hole to a diamond arbor, is there an adaptor I can get for my saw's 1/2" arbor to accept blades with this diamond knockout or am I just not looking in the right place for blades?

buy the bushing if the common size blade has a 5/8 center . the bushing can be used on replacement blades

Yeah, it's looking like that's what I'm gonna have to do. I just hate paying more for a glorified washer than I did for the blade itself. LOL

I needed a 5/8 to a 1'' shim. Menards listed three machinist washer that size for 39 cents each. Of course the box was empty.

Yeah, of course the box was empty. LOL I'd double check the thickness as well though. You don't want the clamp holding the washer in place but having the blade spin around it when you go to cut something. I'll have to keep Menards in mind though, they seem to have damn near everything in there. I've been in about 3 times since I moved up here and I still haven't been through the entire store yet!
Thanks Cobbler, I went with the first one you linked. Truth be told I ordered two of them, at $2 per I may as well.

I sure like diamond arbors; keeps everything nice and simple.

Phew, thank goodness those never showed up in a google search. That might have been useful!

And we have liftoff! These shims just dropped right into the saw blade, no hammering necessary. It doesn't take much to push them out but they fit well enough you can turn the blade over without worrying about them dropping out. I'm still going to grab an assortment pack from Menard's next time I'm in town. Thanks again google.

Just because I'm always annoyed by posts where someone asks for help, seeing advice and recommendations made but never seeing any replies as to what the outcome was.
