Hello,

Your photo resembles the 15-087 housing pivot and the 15-086 tandem housing, which use the S180 coil springs. Take a look and compare the specifications to your assembly. Thanks for posting!

I think there are two springs. One in each housing. Can you advise please?

One coil would install in the 15-087 housing pivot, and the other in the 15-086 tandem housing above it. You'll need to remove the original coils to locate the stamp codes, which correspond to the strength options needed for the replacement S180 springs.
