prop. valve problem

I am upgrading from drums to discs, and as such will be upgrading my MC and needing a new prop. valve. When I bought my 3/4t booster, it came with a prop. valve, but it is definately different from my drum/drum setup. The disc/drum valve has one spot for a line from the MC on top that is smaller than the fitting on the MC, one spot on the rear that is larger than the line for the MC, and two fittings on the bottom that appear to be the same size as the fittings on the MC (I assume these are the same size as the fitting currently on the lines going to the front and rear brakes).

Anyway, can I buy these lines at an autoparts store or do I need to hunt down some adaptors? Does anyone have a pic. of a 3/4t MC and prop. valve......I swear, the way this is suppose to go together looks like its upside down
