Ah, and I've already managed to scratch his craftmanship :P Dropped the lever (just the lever itself). Oops.
Have drilled and painted reinforcement plate, haven't done transmission tunnel yet (drill ran out of battery). Measured, calculated, scratched head, measured and guessed a fair bit - have to make sure when I put the Sprinter box in there I can still use 2nd, 4th and reverse gear :P The shifter sits a whole 115mm further back! I think I've gotten it right though.
Dropped tailshaft, looked at brake lines, bending old brake line to go through floor is going to be interesting. Not looking forward to it...
