Hi Don. I went the same way, Roadster brackets with a Clearview screen. The chrome strips are not sold separately, apparently they come with the Roadster screen. So I got some licence plate bolts from Canadian Tire; they're black plastic with crome bottons for the top. The plastic bolts go in first, and the plastic button pops onto the "bolt" head facing outward on the screen. Looks OK, and the screen is certainly strong enough.
I found that after last year the chrome on the plastic buttons wore, but they only cost a few bucks so are cheap to replace.
