Looks like one of those simple "Bolt-ons", doesn't it? Maybe yours will be, and maybe it won't.

The windshield pillar to windwing mounts can be different. They are little 1/2" x 3/4" pieces. Sometimes they are countersunk and angled, sometimes they are countersunk, and straight. Some use 10-24 screws, others 10-32. Some windshield pillars have a slide in brass strap the windwing mounts attach to (which tend to strip rather easily), and some do not.

I purchased a 6' length of 1/2" square T-6066 aluminum from McMaster-Carr to cut 4 ea., 3/4" long pieces for just this reason. If you find yourself in this dilemma, I have some left over.

And...would advise taking your OEM hardware and replacing it with stainless screws, and stainless locknuts. The rust looks tacky on a Cobra, and having your windwings or sun visors vibrating loose on the highway is even tackier.
