Thank you all for your input. Without looking to be sure, I think the original RR UQP was about 65 inches wide. There was a switch to Argon 90 fabric which came in 55 inch width. As mine was the 65 inch style, I asked that 16 inches be removed so it will be 6 inches narrower than the current standard. There appears to still be plenty of room under the 55 inch version and it wasn’t sized because of the RR, it was 55 inches because that’s how wide the fabric is. So I’m sure my extra 6 inch loss will pick it up a little more but still maintain and air pocket.

You are right about a certain amount of interchangeability. l didn’t request that UQP adjustment for years because I know I had two and the second one was … hiding. Turned out, it was masquerading as a GE UQP on my BlackBird. So not only does the GE work with a Bridge (the RR anyway), the bridge UQP works with a GE. But it was still a little big.
