1940s Kits for Installing a Jeep Engine in Other Vehicles

This Northwestern Auto Parts and Wilenskey Auto parts ads in the January 05, 1947, issue of the Star Tribune out of Minneapolis highlighted engine kits that allowed a jeep engine and transmission (which was included with the purchase), along with the necessary mountings, to be installed into certain Ford, Plymouth, and Chevrolet vehicles. I wasn't aware there were kits design to do this.
