Can Schlage and Yale parts be mixed at all? or others?

[jurvis1]

I have a schlage deadbolt on the front door of my house and a yale keyway on the back mortise cyl. 15/16". I tried using a schlage cylinder in the Yale mortise because I have no used schlage mortise cylinders and it was close, but not close enough. I then tried to find a yale cylinder that might fit in my schlage deadbolt and could not do that either. Yeah, I could just replace the whole works, but I just was wondering if it is possible to interchange parts like this so that you can use the same keyway without having to replace the whole lock out!

No steel door. Old wooden door with an old commercial style Yale mortise lock. I'm a yank. Never heard of Marks. Are you saying that these parts would work? One cam is like a commercial tailpiece like you'd find on a commercial mortise and the other is a straight tailpiece like a residential deadbolt. Anyway I wondered if there was an easy way and since probably not then the only way to go is with another lock.
