I could be wrong but I talked to a few people that put strange rearends in, they say that they are actually dana, even have dana stamped on parts. They had no complaints, not sure what the deal is, some think strange and dana have some kind of agreement, I dont know. I know they're good rearends, but on my budget I run a Ford 9 inch, they're tough and fine with me. Only broke one in my life but I think it developed a crack around third member cause I tortured it, off road and more! I have had dana rearends in the past, and they're fine. Right now I have a dane 70 with 4:56 gears, but its from a truck, would have to be narrowed, but I bet you wouldn't break it!
