Ok. If you want to challenge my credability too. Go ahead.
For me i have been professionally wrenching on cars since 1980 when i got out of the Air Force.
Having worked at a shop here in California that had a contract to work on State of California fleet vehicles, and CHP vehicles, on a rotating basis, i have seen, and worked on lots of different vehicles that this state had in their fleet of cars.
In all the time that i saw, or worked on state fleet vehicles that came into the shop, i never saw a Duster or Dart that had 15 inch wheels or tires on it. If you think someone was going to have fleet vehicles like this, wouldn't you think California would?
And i did LOTS of tire rotations, air pressure checks, and brake jobs, on these cars.
I don't know this guy Bruce, and he doesn't know me, and just because somebody's been posting on some internet web board for a bazillion years doesn't make it right to pass along information to some kid, on this board that now believes he's going to find a 76 Dart with 15 inch wheel and tires on it, or anyone else reading the posting.
No one challenged your credibility. You certainly do get definsive quickly. i neither agreed no disagreed with you. I simply found something that POSSIBLY supported Bruce's statement. Nothing more. As old as those cars were, it's entirely possible the rotors were changed out. Also, you've not even taken into consideration the possibility of a dealer installed option. they did stuff like that routinely. I think there are better things to do than argue. I was not arguing. I was simply saying that it WAS possible. the way the article I posted read, it said the brakes WERE larger for 76. PERIOD. the prior rotors were 10.970" (11"). not the 10.75 that you posted. the 11" are all over Rock Auto, NAPA, Autozone, Advance, bumper to Bumper and all the other parts web sites, so who's giving out wrong info here? Look, I'm not trying to get in a pissing contest. All I'm saying is, with so many made and being so long ago that anything is possible. Nothing more and nothing less. If you think for one second that a sheriff's or a police department could not have ordered the police package cars and then opted to have the dealer install 11.75" brakes and OR 15" wheels as a dealer option, then you are seriously mistaken. that kinda stuff was done day in and day out and still is. So, inevetibly, no one gave out incorrect information except you.
