incompatible with Glidecam 1000 and 2000 - false description - 3/8 instead of 1/4 "fixing screw

Unfortunately, located on the underside of the SK-plate against the description only a 3/8 "fixing screw.
Quote: "be installed on every CULLMANN- and third-party product, thanks to standardized 1/4" fixing screw ".

Have the product was purchased and a description of review due to the (false) in the claims that the product is compatible with the Glidecam.
However, this applies only for the XR 4000 or HD 4000 model, because only these two have also 3/8 "mounting holes in the camera plate.

For my HD-2000, SK-plate is therefore unsuitable and I'm going to set the Schnellwechseplatte the Flycam because this has a 1/4 "fixing screw.
