I've got the standard multileaf GME springs on a 1974 88". Made in Sheffield. I like them, very nice supple ride, everything seemed good quality. They came with spring bushes already mounted. A world away from seized and rusted old springs.
I use them with Girling Authentic Classic dampers. They were slightly difficult to get in place as they are quite "springy" but once in place the car sits fine.
The part numbers of the L and R front springs are definitely different, and the springs are stencilled in white paint with the Land Rover part nos following the words "REF NO" as well as the GME part number starting with "LS". To ensure each was on the correct side I used this number to refer to the parts manual as it states which side is which.
GME is/has been a supplier to Jaguar Land Rover, Morgan Cars, and the MOD.

I can't find the page where it said GME supplies Jaguar Land Rover, but I've definitely seen it.
I called the helpline to ask a question, great customer service, very helpful.
Mine came from gdiproducts, a seller on eBay.
