Seems in recent years that availability of +2 shocks for a D2 has become extremely limited!

Anyone know if there are any adapters that would allow the use of Defender shocks on a D2? Opens up many more options...

Currently have OME +2" but they arent quite good enough for me.
Wont touch Terrafirma again. Britpart likely the same.

Leaves Bilstein 7100s, rather expensive.
Fox -
EFS - Devon4x4 has them and they look good but never heard of them before.

Ideally I wanted Koni Heavy Tracks again but no longer made for the D2. Paddocks only have rears, cant find fronts anywhere.

Never seen that but i would give Gwyn Lewis a bell and see what he can advise in way of adaptors. You can relocate the rear mounts lower and use a normal length shock. Same on front if you get lower shock towers.
