Front Track Width

[66GTDART]

When upgrading 1966 Dart brakes using the later model Disc setup does the track width change?

It does increase, I believe the generally accepted measurement is 1 1/2", 3/4" each side.

Thanks for the quick response. Much appreciated.

I used to own a factory 75 Dart and the wide front track vs the narrower rear track bugged me from a visual stand point but I'm pretty weird so... there's that

Yeah but the narrow track in the rear is as much the issue as the wide front. Especially with a '75, the 7.25 and 8.25" rear axles are about 1" narrower than the 8 3/4's were.
