Kitchen cabinet hinge - can't find replacement

[chantaspell]

Hi
I have a kitchen cabinet door that won't straighten. Investigation shows a wobbly hinge. They are pretty old but I assumed someone would sell them but can't find them anywhere! They are Blum marked 90 255. They are 85mm length.

How difficult would it be to fit a shorter (64mm) or longer (110mm), both of which can be easily bought? Should I go bigger or smaller?

You can replace it with any 35mm concealed hinge, just buy it with the hinge plate

The hinges you need have a 0 crank (sometimes called straight) for full overlay.

Thank you @Notch7!
That is really helpful - scoured everywhere for the "correct" size but will buy as you suggested above from the Screwfix round the corner, if they have stock.
