fitting an R34 RB25DET 5 speed manual "bigbox" gearbox into a Turbo VL Holden Commodore

process of upgrading my turbo VL Commodore from a smaller RB20DET gearbox to an R34 GTT RB25DET "big bix"
Covers the whole process of going from rb20det 5 speed to the big box.
From drive shaft yoke upgrade to changing front cover from pull to push clutch set up and suprise crossmember solution
Excuse the poor quality of some of the clip and one glitch that I noticed after uploading, (what it missed was not importand, just my wife to be coming down in the car on the hoist)
