front wms width and rear wms? 91'

I have a 91' mustang I am fixing to get a tear apart the rest of the way for my 63' falcon.I was wondering if anyone new how wide the front is from disc to disk?Also was wondering what the rear width was also.I am just tearing a vert up so not much loss.Thx for any help with the measurement's or links to the answer's.

The mustang is about 60 miles away at a buddy's house.I have not gone to bring it back home yet.And it is out back in the field so I can't get him to go out and tear it apart and do any measureing.I just figured someone here actually new the measurement's.I am heavy into rockcrawling and can tell you the measurement of almost any offroad axle front and rear and some of the wheelbases.Thx for asking.It helped me get a bump back to the top of the page.
