Before I order my FC750R I've do a lot search to find out the answer to its weird spacebar's stem position. Then I've got two answers:
first is the picture Flyersfan1 posts showing that FC750r can't use universal spacebars but the spacebar come with it seem to be compatible with both Leopold kbds and other OEM ones
second one is here:http://www.leopold.co.kr/?doc=cart/item.php&it_id=1403755947
This is leopold's official site. As you can see clearly, all the problems with spacebars is now fixed. I think there're two batches of FC750r. Only the new ones have the "right" positon to use almost any spacebar we have.
TLDR: 2nd Edition of FC750R fixed the spacebar problem now the swtiches stand at "right" postion as shown below.
