They mailed me back that the person in charge is away some days. Second their info@ had some trouble. Seems to be solved now.

That's right andrew. There is a 110x110 and a 158x158 version. the 635 45A should fit the toyo 45A II.

I saw the chinese also, but first it's not a original one. The bottom is much diffferent as the original. Mostly the pin that is sticking out in the bottom middle where the linhof board fit into is missing with a chinese version. Second i find the price to high for a copied. If they sold it for $30 i would try it out, but since they moved their prices up to get much more profit, i want the original.

Thanks.
