Hi Drake - We use the new style Unirac mids and ends frequently on older Unirac SolarMount rails without an issue. I think the vast majority of systems used SolarMount, but you'll want to verify that you have SolarMount rail rather than something that is discontinued - I think for a while they had a I-beam shaped rail and I have no idea if they make replacement parts for those old rails.
They have a few variants of clamps now, we've had good luck with the Pro Series SM Midclamps and Universal AF end clamps. I think both go up to at least 46 mm, which is a little over 1.8." Good luck!
