I would think one can mod the G2 backplate to fit the 60mm version, but if it's not needed... why bother :p The G2 is definately long enough (I don't get the 30mm/40mm part... the plates are not 30mm/40mm wide? According to Heatkiller they're 14.5mm, and the block itself is 16.5mm wide).

The blocks you're looking at are for mainboard VRMs. The proper ones ( the one's matching the GPU Block) are the ones on this page.

After reading the above link, the dimensions i posted before will make sense.
