After two weeks of being sick...

Went to garage again. Still a bit weak and fuzzy, but in much better mood. So, where we stopped? Ah - the transmission mount. Drilled few holes (because wanted to work it in two ways, like stock), and made it a bit more original :). 034efi stuff is much more harsh (motorsport grade), because it is single movement only (bolt stops any tensioning).

Here is final "product" (rubber appeared much more soft, when pushed with M6 bolts):
Two smaller bolts are holding rubber bound to the aluminium, and big bolt comes through a hole in the aluminium and bolts to the gearbox leg. Between gearbox and rubber there are pile of washers, which also go through a hole in the aluminium.

If the bolts will come through rubber under load, then I think I will add aluminium disk instead of washers. Then rubber thingy only will work as flexible element. I can replace them every week - price is only 2euro in local sport's store...
