I own a 1976 300D and enjoy it alot. Recently its been having some engine trouble forcing me to rebuild the engine, or junk it. I know the car itself isnt worth all that much. I found a 1991 300 2.5T 5cy. diesel engine for really cheap with about 89K miles. Would I be able to drop that in place of my '76 diesel 5 banger fairly easily? My '76 is a w115 and I think the '91 will only work with the w124, but I'm not sure...
