Demon Carb

Bought a 850 mighty demon on E-bay a week ago. Seemed like a good deal at the time. Carb looks really nice, but the 3 of the bolts that hold the bowls on are stripped out on the main body. My question, Is there a fix for this or will I need a new main body, There are alot of replacement body's on E-Bay but nobody seems to know if they will work on a Demon carb. Shouldn't the Demon and Holley be the same body? THanks Rick
