S3, E20: A gang of "strippers" is on the loose: a band of men who go around stripping cars of various parts. Jon and Ponch are baffled as the parts being stolen are not showing up in the usual places. The operation is a slick one: the culprits strip the cars of all their parts, then buy the chassis at an auction and reassemble the car. They own it then sell it for new, legally. All of this segues into Jon and Ponch's skill at sky-diving, and they're able to crack down on a heroin ring that flies the drug into the U.S. from Mexico.
