Default Driveline vibration in low gears (245 Torslanda)

Hi all,
I've owned my Torslanda for several months now and am gradually getting all the little kinks ironed out. It's a beautiful car and I'm really enjoying owning it, but still have a couple of issues to sort out.

I recently had a new clutch, engine mounts, gearbox mount, rear main seal, aft driveshaft UJ, radius arm bushes and torque rod bushes fitted, which has eliminated 99% of the judder that I was getting when pulling away and the resonant oscillation I was getting at around 55mph.

However I still get a slight vibration/oscillation when pulling away in first or when I change to second slightly earlier than I should. I'm thinking I should change the foremost driveshaft UJ and driveshaft centre support bearing to eliminate any other potential driveline issues. Beyond that, the only potential causes I can think of are gearbox output shaft bearing or diff pinion bearing.

Does anyone have any thoughts? The diff is silent and the gearbox works smoothly and isn't losing any oil, so I'm not treating either out/in bearing as a prime suspect.
