Well done Jon and i think i would do the same and leave the output shafts alone.
Don't take any risks

The old Drive Shaft ears will bolt direct to the Diff Output Shaft ears. Drill a hole in a heavy bit of metal so it will slide on the old Drive Shaft. Put the Hub Nut on the old Drive Shaft and a big washer for the heavy bit of metal to slide/hit against.
There you go a home made sliding hammer

Typically bearings come open, with metal shields ( metal shields in SKF terms is 2Z) or with rubber seals - you want the ones with the rubber seals.
Its a poor design by Lotus to have the diff output bearings exposed like they are with just the bearing rubber seal protecting the bearing from the dirt and water under a car. At least on the wheel hub they put a metal shield over the inner bearing and the hub provides some protection for the outer bearing

Sure those are genuine? There is a lot of fakery about. Also, the sizes are quoted in metric. Will they fit properly onto a shaft machined to an Imperial size?
Example: https://www.ebay.co.uk/itm/222302435128 are SKF 30x62x16mm

2 RS Bearing with rubber seal on both sides. RS provides a better seal but more rolling friction than 2Z.
RS Bearing with rubber seal on one side, one side open.
2 Z / ZZ Bearing with a metal seal on both sides.
Z Bearing with a metal seal on one side, one side open.
E Reinforced Design
P2 Highest precision
K Bearing with taper bore
The seals are just about OK for retaining the bearing grease within but not really for resisting external contaminant ingress or hot diff o?l, the exact same bearings are used on my Maytag (American) commercial washer but they are protected by additional external Gaco type shaft seals, when these break down and allow the bearing seals to be exposed to water they in turn fail very quickly.
