D4 Shock problems

[Chesty]

Just wondered if anybody else had encountered this problem when building the car, or is it just me!

Built the shocks following the instructions to the letter, using the two supplied plastic tools to fully tighten each end.

Now, when I go to take them apart (to get them just right) the shock top unscrews before the cartridge does, every time!

I need to get the cartridge loosened to bleed them. I don't want to grip the shock body in case I damage it.

Apart from this the car has been a joy to build.

Any solutions or tips would be greatly appreciated.
