Whitefish, at least one member I know of has modified one of these Fulton visors to fit another year truck, but that member is no longer around (that we know of). The member was Sanidande and later on morphed into JuliescoolF1 You may or may not be able to search for the pertinent thread(s) using either of those names, perhaps get into their respective galleries.

My avatar, along with the signature at the bottom of my posts , is my way of honoring this dearly departed member.

The visors are frequently available on eBay, along with the mounting brackets you'll require. Also, post your request in the 61-66 Forum, you might get help there. Finally, there are a few guys in this 57-60 Forum who will have more fab skills than me, and they'll be along shortly, and might respond. Good luck, Steve.
