Four Prototypes were produced from 1975-79. One is in a museum, another is in a private collection and the other two are lost. Although they ran circles around the Audi Iltis in test races, VW had too much of it's budget wrapped up in the new T25 to fund Syncro production until 1983. It has been suggested that a Bay could be mated to a Syncro drive train. Besides the obvious suspension lift and custom front mounts, it would probably need the T25 steering and front suspension, raised engine, custom drive shafts to accommodate the T25 wheelbase's added 5', and God knows what else. The T2 Syncro had 16' rims and the exhaust was raised and routed through a hole in the bumper for added ground clearance. Take this information with a grain of salt. I just skimmed it quickly and carelessly from other sites and forums while most of my attention was on fervently dreaming of owning one of these bad-asses.
