Comin down to a money crunch

What it comes down to is the $3100 I was going to spend on putting a moser 60 in my car is being spent on the trans and engine on things I wasn't expecting to spend it on. So my options would be to delay the project or buy a rearend locally and it is a ford 8.8 with.bb a TA girdle new 4.10 gears a 31 spline mini spool, strange axles,disc brakes w/ calipers and a 1350 yoke Width wise it will bolt right in and allow me to use 10.5 inch tire with my mini tub job . Rearend brandnew no passes and the guy wants $500 for it is it worth it??

Thanks, for your input guys .
