Girling shock absorber part numbers

[M25VAN]

I'm trying to source alternative part numbers for some Girling shock absorbers. The Girling application list (G311/7?) doesn't appear online so I'm a bit stuck.
They're for a Portafold caravan and have "Girling Patent NA64054429 ADX" stamped on the body. I could probably find a match for the dimensions but would like to know I've got the correct damping rate.
Can anyone help at all?
(Apologies to those who would prefer the term damper )

Have you compared classic mini shockers.

Thanks for that Bill, I'll keep that in mind. I wonder why there's so little information in the wild about Girling dampers for cars? Plenty for motorbikes.

I've got some leads on Herald/Spitfire/1300TC dampers fitting and there's unbranded of those readily available. I've read that the mini dampers are too short unfortunately. Will keep searching for branded and compare sizes. Current ones are definitely shot so I have to find something.

If you compressed and extended length and eye size you should be able to find something, Armstrong and spax common for older cars. Have you looked at carbuilders solutions online site.

Yes, just waiting on the sizes of some Triumph 1300TC dampers. I don't think I have Herald /Spitfire ones as there's no fitting for the coil spring.
Nothing on Carbuilders but they have something else I need so good suggestion.
