Tub and spring relo

Wow! 44" that is really narrow. There are ways to measure wheel offset and tire size with tools they sell on the internet or you could use the coat hanger method. I built my rear to work with my tires and wheels.
I am just finishing up the mini tubs, parallel 4-link, new axles, installing my narrowed rear and disc brakes on my dart. My rear ended up being 54.5" hub to hub, but I run quite a bit of +offset. It is a very tight fit with 12" rims and 325/50/15 drag radials. After trimming the fender lip I have about 3/4" on each side. I am a little worried about rubbing, but I am hoping with the 4-link and track bar the rear shouldn't move at all. I will see if I can find some pics.
