All ready to go together. As a little bit of added security I decided to locate the bearing with a 3mm grub screw engaging the existing groove in the bearing. The screw shows up better in the flash shadow than it does on the actual pump. I also took the opportunity on reassembly to close up the impeller to housing clearance. I have never liked the big gaps found in most factory waterpumps. Final overall length of the pump to the front of the shaft 4.9". This means I won't need to put a power bulge in the firewall to enable clearance for the pump or for belt replacement. Sweet!

Not bad considering the extra length that Porsche have in the 930 from the driveshafts forwards and the extra 10mm that the motor plate spaces the pump forwards.
