You can see mine in my sig pic. I backed out one of the alternator bolts, slipped it through the hole in the catch can bracket, then reinstalled it. The can isn't in the way of working on anything else, is easy to reach from the side and has plenty of room underneath the hold a cup to catch the drainage.
The one I put on my brother's truck was one from Amazon and it didn't have a bracket, either. I made a simple one out of a piece of 1.25"x.125" flat bar to mount in the same way as the one on my Tahoe.

do you guys think I should add a check valve to the breather hose side?

looks good. probably gonna go tomorrow and pick up some 1/2 and 3/8 heater hose at autozone tomorrow and a couple of barbs. the catch can I have has 1/2 fittings on it
Generally speaking, I think best practices would say avoid using heater hose, in applications that involve hydrocarbons.
Another thing to consider is this application is under a relative vacuum, so a thick walled fuel supply style of hose may help in assuring the line doesn’t collapse under vacuum, especially as it ages. The runs to and from the catch can will probably end up being pretty long.
The OEM line that runs between the PCV and the intake manifold is plastic hardline for most of its length, with only the ends being rubber hose to make the junctions (very short runs).
If it were me, I would use a nice sturdy 3/8 fuel supply hose and update the fittings on the catch can to support that hose.
Having said all that, as long as you keep an eye on the hose and make sure it isn’t collapsing on you under vacuum, the rest might qualify as dancing on the head of a pin stuff.
Best of luck, whatever direction you choose.

My catch can came with 3/8 and 1/2 barb fittings. I used the 3/8 ones.

I was thinking of stretching the 3/8 hose over the 1/2 fittings and using hose clamps

If that works, go for it.
My 3/8 fuel line hoses were pretty tight getting onto my barbs.

last time I had to do something like this I soaked the ends in warm water then stuck a needle nose into them to kind of stretch them out and slipped it on real quick
