They are all the same back set. When I install them I cut the 32mm hole then assemble the lock, this way I can still move it around a little to get it to latch nicely, once I get it where I want then I will drill the holes for the screws on the body. You are better off replacing the lock though, the newer 001 are a lot nicer, or even better a 303/ 355.
My only gripe is that it takes forever to re key the inner 001 cylinder and that sometimes the safety release stops working after a re key (even though it's in the correct position etc)...
