Hi
Im looking to replace the gas struts (air springs) on the guard door of my Emco vmc100, I have sourced a gas strut supplier which can suppy them for about £20 each, but I need to know what force in NM they need to be, the range I have been offered is betwwen 50 - 750 NM.

There are no marking on the originals struts, but I do know the Emco ref no. which is 'ZFD 30 0080' does this mean, 80NM??

Any help would be greatly appreciated, thanks.
