Eddie,
Can't say for certain about that flasher, but it looks like it'll work. The one I posted above from Advance Auto is the one I used, so I know for sure that it's works.
As for the bulbs, they don't have any side-firing LED's, just rear firing. So in my opinion, they're not going to be as effective. With a totally rear-firing bulb, very little light is going towards the reflector, most goes straight out the lens. You really want as much light as possibly in the reflector to fill out the tail light and make it the most visible.
I know the side/rear SMT bulbs are more expensive, but sometimes you do actually get what you pay for. I've tried both, and these are much better, and were (in my opinion) worth the extra $$$.
I've no idea if the 922 will work in the CHMSL. I have the Recon LED CHMSL from Zabteck.
I'll try to take some pictures of my rear lights this weekend and post them. I've changed the tail lights in the last year, so the ones currently in my library aren't an accurate representation.
