Need quick release plate for Canon XLH1
 

I use a Really Right Stuff BH55 ball head on a Gitzo tripod with a RRS lever clamp to support all my photo gear when I do landscape photos and videos. RRS does not make a quick release plate for the Canon XLH1, but they do make one for the XL2. It attaches with four small screws on the bottom of the camcorder. It looks like the same screw pattern as the XLH1, but I can't tell for sure.

Does anyone know if the four small screw holes on the bottom of the XL2 and XLH1 are the same?

Thanks.
