The *easiest* thing would be to install a new engine. Here are a couple from ebay:

Otherwise, I think you may be in for a ton of trouble rebuilding. Is only the case damaged? This guy is selling a couple of cases, but not what you need exactly. Maybe contact him and see if he has one for your engine:
