8 3/4 rear end/Dana 60/8.25

I need a stronger over and for my 1972 dodge dart. I'm not opposed to putting anything in there as long as it's bassically a bolt I just turned 20 I don't know a bunch about cars so cutting down and welding a rear end together isn't an option for me thank you
I have an a-body 8 3/4 with small bolt pattern axels, 741 3rd member with 3.23 gears, and backing plates need brakes and drums I'll be at fall fling too if you are interested $550. Thanks David
