Just got my 84 300SD running like a new car( thanks Kent) so on to the next project. A mint 76 300d that broke the timing chain after the previous owner replaced it. I have 2 options... a used unknown engine(already out of the car when I bought it) of the same year with 150,000mi? Or a 84 turbo running in the car(wrecked) with 220,000. My question is will the 84 turbo fit in the 115 chassis? Any ideas? Also any way to run the other engine on a stand so I don't transplant junk for more junk . Thanks Jon
