You need to define what years , because there is a difference in the front wheels track (width)between 70-72 and 73-76.
The 73-76 is wider because of the bolt pattern change, it added 1.25 inches because the factory switched on B/E front spindle/rotor setup instead of making an A body specific setup as a cost savings measure. The switch in the rear only added about 1/2 inch.

And when you "upgrade" to disc brakes on an earlier A-body with the 73 up parts... your front wheels are noticeably outward! Take a look at your local car cruises, you'll be able to pick them out. Well, maybe not where you are....

Yep... I've noticed this with my '68 Dart. I'm trying to fit a 9" wheel all around. I've got +73 Disc brakes with a Doctor Diff kit in the front and an A-body 8 3/4 with bbp and his disc brake kit in the rear. In the front I need about a +30mm offset and the rear I need about a +18mm offset.

MMMMMM interesting!!!
yes I was talking about 73 and lates. But I thought was also something common on earliers
I think diff is way more than an inch ?

Have you looked at actual factory specs or gotten out your tape measure and actually measured it ?
I'm pretty sure it's not the only model that the track width is wider on the front than the rear and it may have been done that way for a reason ?
Have you asked this in the handling forum, they would have a definitive answer I am sure.

no, just asking about what visually is obvious... and reason why could be. Never though could be the front disc setup making that, but wondering if also another reason now

Hard to see 67/72 A bodies still with front drums locally. They are normally already converted, since they use to be daily drivers, so disc conversion has being a common demand for them

The track width shouldn't be different drum vs. disc when original model year correct parts are used.

The tracks vary from early to late.
Go here and look through the Data books for each year. Track widths are listed 67-72 being one and 73+ being another.

It's when you put the complete '73 up disc brakes on a 67 to 72. It's very noticeable, and wrong size tires will hit the fender.

Just curious... What rear end do you have under there? IIRC, the 7 1/4, 8 1/4, and 8 3/4 were all different widths drum-to-drum. I could be wrong.

Re: question about 70s Darts width between wheels - 01/09/15 04:10 PM
I think 8 1/4"
8 3/4 wasn't available to A bodies since 73. I think 8 1/4 was the bigger

Look at the rear of your car if there are bolts on the housing then it's either a 7 1/4 or 8 1/4. The 8 1/4 is more oval looking. If it's smooth and half a hemisphere it's an 8 3/4. I don't believe they're all the same width.
