hi all,

currently carrying out some bodywork on my 1980 westy poptop and need to remove the sliding window from the sliding door.is there a special way to remove it? i.e is it fixed by screws etc. or is it just the usual method with a couple of screwdrivers and perseverence? any help as always greatly apprieciated

cheers mel.
