Cupra PD160 clutch change -- Weight of gearbox?

[Rioja Cupra]

I'm about to embark on a change of clutch. Should be fun.
One part I'm unsure about is dropping the gearbox (literally).
It's a very strong 6 speed box, (O2M I believe), therefore it must be heavy. Does anyone have a figure for the weight?

Found it in SSP_205.pdf
Weight: 48.5 kg (front-wheel drive) 68 kg with angle drive (four-wheel drive).

I'm glad I found that out now.
It looks possible to split off the straight through drive, under the engine, where the driveshaft is attached. That will lose a few kg.
Some thought required methinks.
