This is precisely what they've done to me to put things right........(tho mine does have 4 lower screws to accommodate my larger arse)

Impressive these physicians..... Even asked me what colour I'd like it in (red naturally), but unable to confirm the supplied colour match.
God, you can tell the morph's kicked in again.........
Seriously tho, thanks for all the kind words. I'm home now, starting the, hopefully, short road to recovery.
