Which one of these is the original spring..?Both are about 10.3cm x 5.5cm.

Hi Brandon

Its possible they both are, but the ones on my M20 have 6 coils like your left hand one.

Thanks Rob.

I just checked mine. They are also the same as the one on the left in your picture with the fewer coils. Ron

Thanks Ron, that confirms it then.....will get a new set made up.

what about compression rates would they be different i could do with some stronger spring for my dainty little bottom
