So I kinda zeroed in on that one, but couldn’t make out from pix if the holes along the side were decals or holes; I assume they’re decals or paint.
The recommended part# I finally found, as in your document, is 3308047.004, but it did look like your 3308047.012 would work if the holes lined up and nothing touched on the inside.
My originals are flat on top, but the “Penguin” (yours) version has swept “moldings”. As long as the screw holes line up. Mine are also painted “platinum” like one of the sidewall colors. If replacements can accept paint okay and I can match cheaply and closely enough, I might paint new shrouds. But on the roof who’s gonna notice. Hopefully newer versions are far more UV resistant, but covers during storage here at home should help that too.
A year or less ago the than advised replacements were $125, now they’re $172.
