Please keep us updated on your progress, and if you can please take a lot of pictures and post them. This is a swap that I I'm considering myself. I mainly for the better brakes. I plan on towing a lot with my 4x4 93 Ranger.
Also to respond to your question about the increased width; from what I read in the article on this site, about that swap, that increased width is a bonus, because it's going to have a different bolt pattern then the ranger wheels, so its recomended to put adapters on the rear axle to match the bolt pattern of the front. Thereby increasing the width of the rear axle also which probably closely evens everything out.
That's the only thing that bugs me about this kind of swap. I'd have to get all new rims. I have a set of all-terrain tires on rims and a complete set of snow tires on rims. I couldn't use those anymore.
It's unfortunate that we don't have better brake upgrade options for arrangers other than the knuckle swap from early style Rangers to later style Rangers.
