Lone time gone - Front end question

Hey guys,
First post here in years. My son and I embarked on a 72 SWB rebuild that has taken us almost 3 years. After swapping from a 360/C6 to now a FI 5.0/AOD, we finally got it running!

Question is about front end. I changed over the drum brakes to a 73 disc brake setup. Did this change my front track width?

Seems like my front end is several inches wider than the rear end track. about 4" actually.

Is this right?

Is correct, but you didn't do it. In 65 the front track was widened with the Twin I-beams. It was 73 that the rear was widened to catch up.

So all 67-72s are wider in front track than back? I didn't know that. My options?
Leave as is?
Deeper rear offset wheels?
Replace with a 73-78 Rear end?

The width between the rear frame rails (behind the cab) on all 1961/72 F100/350's is 33 1/2 inches.

Beginning in 1973, the width between the rear frame rails is 37 1/2 inches (except on 1973/77 F250 4WD's and 1973/79 F350's on the 140" wheelbase ~ that are still 33 1/2" inches).

Because the rear frame rails are wider, the axle housings used on these later trucks are also wider.

Actually it's 65-72. I can't help with your options, that is your decision.

I never noticed that... I went back and look at a bunch of F100 pics and yeah, you can see it when you look for it.
