Hi Alain,
>couple of rear hatch struts to replace

It's as easy as it looks. There's a circlip on the van end (a little springy,
washer shaped thing that slides on and off)
and another "pry on and off" spring clip on the door end.

>couple of window cranks and these look like they just pop in to
>the shaft: does that mean I just pop the old ones out? I can't see any
>screw, or other retaining device, can someone help please.

The window cranks as I recall (and solicit correction from the list as
necessary)
have a screw holding them on. It is revealed when you gently pry up the plastic
covering the crank. Once this screw is removed
it can take a lot of patient prying to get the old crank off -- but it does just
come off once the screw is out.

Cheers,

Doug
