Just a guess really, but if it's Peugeot based, then try the Tata range of pickups and jeep lookalikes. They use a Peugeot block as the base, and are fsairly rugged old fashioned diesels. May just be that they're similar.
Hopefully I have the answer. The only vehicle this engine was used in was the 1972 to 1979 Peoguot 605. But forget that, give Paul from "Coastal Rides" a ring on 01797 364757, he reconditions the AQD32's all the time. I have two of them in my Princess and one spare just in case. If no luck with Paul get back to me, I may have another source. Good luck.
