alternatives to an 8.75- what about an explorer 8.8?

not sure this will help but i put an 8.8 in my streetrod mine came out of a lincoln because i needed the bigger hub to hub size from what i read they are a very good rear guys are running the in 10 sec. cars pulling the front wheel of the ground but why did i choice the 8.8 the big reason was dics brakes and they make 2 different dics. brakes set up for that rear one is a drum in the rotor (i didn't use that style) the other uses a different calipier that the e-barke is hooked up to a cam built into the calipier that the E-barke cable hooks to when you put the e-brake on it clamps the calipier to the rotor and i like it
