This '51 Citroën Traction Avant became a Propulsion Arrière
You might know there were import restrictions in Brazil from mid-70's until '90, so it was hard to get replacement parts for old import cars. Sure it would make more sense use a VW Passat B1 (a.k.a. Dasher) transmission with the rotation reversed and the water-cooled VW EA827 engine into a Citroën Traction, but a salvaged Beetle used to be cheap enought to justify all the cut-and-weld required. BTW an uncle of mine had a Simca 8 reassembled over a Beetle frame, and many other French cars such as the Renault 4CV (a.k.a. "hot ass") and a handful of British cars from the years of austerity were repowered with Beetle drivetrains in Brazil during the 70's and 80's.
