The bell housing bolt pattern looks awfully similar to the M102/103/104/111/OM601/602/603 bolt pattern. If you're trying to install it on one of those engines you won't have any trouble. The engine will accept either single or dual mass. flywheel. My 87 bolted up to a dual mass without issue. There is a single mass flywheel conversion kit designed for the early sprinter that left the factory with the problematic dual mass sold in europe that should work with this transmission as well. Theres a lot of info on that kit on the STD forum.
EDIT: single mass kit
