Will do on the pictures. He has every doc and receipt Bill of sale shows he bought at jack dykstra ford in Lansing on 19oct65. $ 2685.14
It is in n Florida now
I have read all the quirks to these bins, but would value all guesses on where it is on estimated survivor lists by vin. Mostly as I have a friend with a 75 bronco and I can’t compete with him on any other level. Definitely not what he paid and definitely not horsepower!
It's very hard to tell. The list of earliest known Broncos has changed a lot over the last 5+ years as these rigs have gained more attention. My friend has #733999. When I realized his truck was so early (about 7 or 8 years ago) it as just outside the top 25. There have been so many discovered since then he's probably around 50+.
Regardless of where it falls on the list, yours is VERY early in production. In my opinion, the historical coolness and uniqueness of your rig puts yours in a different category from ANY 75 Bronco. There aren't many factors that make an early Bronco "special". There are a few trim options/color options, Stroppe's, U13s, U14s, and the early Budd Broncos that are special. Otherwise early Broncos are kind of all the same. Just my opinion, fight me.
If yours has it's original hub caps, sheet metal air duct, rear view mirror, or horn ring, you have a very rare, irreplaceable, highly sought after accessory that has never been repoped (except a few air ducts).
EDIT: If his is a Denver Bronco Edition 75 then he has some standing here. I forgot the DBE's were 75s lol.
