Glad to hear that worked out for you. I've had several Linhof rollfilm backs, and the details can vary, but one nice thing is that inserts are interchangeable among backs of the same model and rollfilm format, so if you have a 6x9 120 back for a 4x5" Super-Rollex and happen to find a good deal on a 6x9 220 back for a 2x3" Super-Rollex, even though the 4x5" back won't fit a 2x3" camera and vice versa, the inserts are interchangeable. This seems to hold true even between earlier tan Super-Rollex backs and later black ones. I don't think you can mix and match inserts between Rollex and Super-Rollex backs, though.
