Yokomo worlds servo problem. Help
 

I have an older Yokomo and I got it without a servo. The holes on the chasis wher the servo should be mounted are at a weird angle. When I angle the servo to approximate how it would be positioned if it were mounted, there doesn't seem to be enough room to fit. Also it makes the arm swing at a weird angle. Am I missing a really unusual part that straightens it out? I servo taped the servo in straight, but with the torque I lose precise turning due to the servo moving on the tape and not being screwed in. I don't have the manual either. What's the deal?
