ok terrific..am i sitting on a bomb now?

[LX XLR8R]

lets see for starters..i dont know how to put this..well basically i blew my rear doing powerbrakes..didnt strip the gears, didnt break an axel, i literally ripped my pumpkin in 1/2, and my passenger side axel tube ripped out!!!!!!!!

ok now for the question..i put in a '90 7.5 rear out of a 4banger AOD convert..it seams to have 3.73's in it..how strong is this thing???does it have anykind of posi in it or is it a open diff???i mean this is the rear that the 5.0's used till '85 aint it??basically do i have to baby this thing or will it handle the measle power that i have
