Stop in for a cup of coffee

I had a good one last night. I picked up a 8 1/4 rear over the summer for a housing to build my rear out of for the dart. I started stripping it to start on the new build, 3.73, suregrip, disk brakes. to save some *** pain instead of doing it on my back. It turns out I cannot use it because it is a 2.45 gear ratio which has the biggest pinion gear I ever saw and the input is offset. I pulled the dig out since I have someone that needs one, but should I get rid of the housing or save it since it is a weird one.? At least it has 2.5 backing plates I can sell to get my initial cash back. I tell you the pinion gear is the size of a softball!
