Sort of sounds OK? An inch - wow! After retracting the three secondary collimation screws, all you had to do was pull the Secondary mirror a bit up the tube with the central screw, then push the collimation screws back in. Is the compression spring still in place?
You need a 2" 35mm extension tube. Bintel sell a GSO one for $39. I seem to recall that they have an internal "lip" that may prevent some 2" eyepieces/barlows from going fully in.
It's a bit unusual that the new focusser needs the extension tube. Is is a "low profile" focusser?
