Identifying my Current 15 Inch Wheels - and thoughts about wheel replacements

so, my duster's 7.25" is 57.125" wide, drum to drum, assuming your rear is about the same. IF you like the wheels, but want to tuck them in, here are a couple potential lower cost options that might be cheaper than new rims:

if you get an explorer 8.8 rear and do the trick where you shorten the drivers side and use 2 pass side axles, that makes a rear that is ~56.625" wide, effectively adding 1/4" of backspace per side, it doesn't look like that will be enough....

But.....

do the same to a '93-up ranger 8.8, and you'll end up with an axle 55.5" wide, which would effectively add ~13/16" backspace per side....

these axles in yards are cheap (about $200, probably another $45 for a donor pass side axle shaft), rangers '97-10 are predominantly 3.55 or 3.73 ratio, some can be found with limited slip, and most of the ranger 8.8's are 10x2.5" rear drums, so it shouldn't upset your brake bias/balance. non FX4 rangers are 28 spline axles, 2002 up FX4 and explorers are 31 spline.

IIRC the axle centerline to u-joint centerline are very close in length to an 8.25 and 8.75 axle, so you probably wouldn't need to shorten your driveshaft....
