That's awesome. I've loved hearing about the different conversions people have done, the motors are definitely slugs but equally unique. There's a company called Wilcap owned by Tony Capanna back in the day, and it seems to me that he actually came up with the idea of putting those diesels in darts, his company manufactured the adapter plates and I have reason to believe that the dealerships ordered up the adapter plates or the engine/adapter plate/transmission altogether to do the conversions. If you go on to Wilcap's website, there's actually info on Mr. Wilcap's interest in these diesels, and it even mentions him building a diesel dart with a turbo and running it in an emissions rally back in the day. I've done a lot of research but I still can't be sure if the adapter plates or the whole setup was purchased from his company by the dealerships, but it makes sense to me, as he had a close friendship with the manufacturer of those diesels. Pretty cool stuff.
