Listen folks, This guy may be confused about the 9" rear, I mean there is no diffrence in the 8 and 9 visibly... He may be confused about the Air Brakes... (likely Air Shocks)... And, he may be confused about the 4V on it. (Ford did not make a 302 4V after 1971)
MY 1971 Maverick 302 2V C-4 8" rear that I owned from 1983 to 1985 (The first car I ever bought with my own money)
Was WHOOPED every weekend by a 1971 Maverick Grabber with a 302 BOSS and a 4V on it. I swear to God! Honest Injun!
It was that Beautiful Blue they had then, it had the Air Grabber hood, Rear Traction Bars, Giant 60 series 15" slick looking street tires, little 14" pizza tires on the front, even the hood pins looked good on it.
I raced him outside the town of Cleveland Utah every time I drove past if he was outside washing it. It was brilliant! It was a BOSS and it was a Grabber, and it was a 4V, and it kicked my ass lots!
The stranges thing is the kid and his father bought the car from FORD with the BOSS in it!
Special order maybe?
By 1975 the only boss out there was Boss Hog on re-runs of the Dukes of Hazzard....
