90 Rear Springs - the wrong ones?

Hi All,
I have the rear suspension off my 1987 90 Daffy whilst I underseal and repair some rust spots. The car was new to me couple hundred miles ago so I don't have much experience of it but it certainly handled like a dog and is a very hard ride. So before I put the whole rear suspension I thought I'd check the shocks and springs.
The shocks are the Brit Part super-gaz, one is more easily compressed and hisses when compressed.
The rear springs though are orange in colour, both are of equal length(!) and have an uncompressed length of 365mm.
Checking online for an 1987 station wagon it appears it's normal for uneven lengths and should be in the region of 400-430mm when uncompressed.
Does anyone have any views?

I've found that Britpart do orange 'lowered' springs which are -1", so these could be those. But should the left and right be the same length?

Drivers side springs should be about 1/2” longer.
To account for the driver, and fuel tank etc.
In practice it doesn’t really matter if the springs are the same length. 2002 td5 90 county hardtop

Thank you, do you know if the 1987 era of defender had rear anti-roll bars as standard?

Ref roll bars a 1987 SW Ninety doesn't have them - and the original chassis doesn't have the mounts.

With harsh ride I'd start with and get rid of those Britpart dampers, ensure tyre pressures are at comfort settings (28 front, 30 rear unladen) and check your bushes aren't knackered.

The springs sound about the right length - they may just be HD which won't help the ride quality unladen at all. JB

I would be investing in genuine springs, you cam probably pick up some tdci takes off on here and then add OME shocks. Cheers
