How much is needed to change the suspension from hydro to dry?

I've got a set of full old dry front and rear subframes and everything to go with them, but they are not in the greatest condition so would prefer so swap it all over into the better condition hydro subframes, any modifications needed?

Cheers people!

The upper arms are different (it will make the suspension stiffer if you use these), but you may use the lower arm and the tie bar with no hassles.
The front subframe differs in the way the rubber cone seats in the tower, but people have long converted wet to dry by sticking rubber doughnuts into the hydro subframes. I can't comment on how well this works, I've always gone the extra distance to change the subframes out if I have to..

Rear hydro frames are sililarly different to the front, the so too are the radius arms.

so different rear arms?

The wet rear arms have no provision for the lower shock absorber mount which is needed. Can change the stub axles but be easier to source dry arms. The wet subframes need some small mods where the hydro bags slotted in, bend the tabs out so the rubber cones will seat properly.
