Original Rear end type on my 70 Duster

I don’t think that the axle was dependent on the brakes the car was built with. I’ve owned manual front disc cars with 7 1/4” axles. One weird one was a 73 Duster 318-904-7.25 with 2.76 gears. Stripped car, too. No front sway bar, Rubber floor mats, foot pump for windshield washer, no A/C, manual steering. The title stated in capital letters: PRIOR POLICE.
I never found out what that meant.

Right, and my ‘71 Dart GT had 10” drum brakes front and rear, 318/904 and an 8 3/4. Actually I’m pretty sure both my GT’s had 8 3/4’s, both were 318/904 cars. And based on the fact that the entire driveline was stripped out of the second one, along with the buckets and console lead me to believe it had the 8 3/4. If it had a 7 1/4 I bet they’d have left it. But it was an LA plant car so no buildsheets and no other way to know.
