rover coils

[87xj95disco]

was working on the rover replacing steering ball joints and some others
and took it for and allinemant an noticed that the d/s coil is different
then the rest of the other. the coil has less spacing then the rest.
the guy that helps me work on my rover works for hoaks 4wd for 20+
years and never noticed it before.
any idea why mine is different then any others out there.
thanks

more weight on the drivers side. I have a spacer on my driver front spring on my 90 to keep the truck level.
