Just finished doing so. ACE 27.1, but no real difference. Founds some darkening shades on Amazon, trimmed to fit. One difference is we split each side right at the windshield pillar (velcro joining). That way, we can close the sides, or leave them open while closing the windshield. Much more flexibility in closing out the sun while keeping the view. No pictures; bus is in the shop right now, but if anyone's interested, I can get some.
Pretty cheap; took a long weekend to cut to fit and stitch together. We added about double the I-beam gliders, as well.
