Both images are std fittings for a Series 2A 88" & 109", the Series 3 would only have it fitted to the front differential as the rear has a Salisbury, which is a completely different design.
As for the axle limit straps, they are as scarce as rocking horse dung, so whatever you do don't throw them away. Try to source some other material to have them remade, be careful not to fall into the novice crack ( I know you have a long standing military vehicle background) with Land Rover parts, as axle limit straps are available, but ONLY FOR Civvie types, they are too short, hope that's of some help, cheers mate Dennis
