OK,
Fellow Burb-n-ites,
All after market visors were direct bolt-on in their day.
I used a car version on my last truck and only if you v-butt the window glass can things get tricky to keep it from flapping.
I do know where there is 3-4 of both styles of visors at a old salvage yard near me and I can go by next week and see about the $$ for you guys if you want.
