If you can keep a secret the Explorer rear end has ratios from the mid 2's to around 4.10 and looks just like a lot of Chevy and many others that had a Spicer type rear. Even has the #%&@ "C" clip rear axles and is narrow so wheels can be spaced to fit. The best part is it has the Corvette style rotor that has the brake drum inside it so the E-brake cables run out of the backing plate just like old cars/trucks did. Dallas Mustang had one in their 1500hp twin turbo drag car with big slicks and it gave no trouble. Of course it had a "C" clip eliminator kit. Dirt cheap at salvage yards.
