Looking for options to do a 4” to 4.5” bolt pattern swap all around and brakes.

I'm working out what to do on my duster for a rear end. can't find much older than mid 90's here. '93-'10 ford rangers are just under an inch and a half wider drum to drum than the stock A body 7.25", and YJ wranglers (the square headlight version) are supposed to be about the same width (58.5"). the dana 35 in the wranglers have a smaller axle tube diameter, so they likely will work with the stock 7.25" shock plates. either will require cutting off the old spring perches and welding new on. the Dana 35 is a 7 5/8" ring gear, the rangers came with either 7.5" or 8.8" ring gear rears. the 8.8 will take just about anything you can throw at it, street car wise. the ranger pinion is offset about 2" from the centerline of the vehicle.

stock '73-76 A body disc brake cars had 11" front discs and 10x2.5" rear drums. '87-89 wranglers had 10x1.75" drums, '90-95 had 9x2.5". 9x1.75" or 10x2.5" rear drums. Also read up on this thread about explorer rear ends:
