We scored huge when Steve Magnante spotted a '72 Gremlin in a Wilmington, California, wrecking yard. It was a 304/904 car with the M20 rearend in it. The M20 is an 8.875-inch differential that came standard in AMC V-8 cars. We were hoping for a Twin Grip limited slip but it is actually a 2.73:1 open differential.
