Progressive Springs

[Joshwuh]

I'm having a hard time finding anything to do with progressive springs and our bikes. I assume I am just overlooking something. I can't even find the spring diameters via the Haynes manual and Google but did a rough measurement and concluded that I'm looking for 25mm or 26mm. Can anyone confirm this diameter? Further, does anyone know which model of progressive springs fits our bikes? On Amazon it only lists the bikes that it does fit in lieu of listing the actual diameter. It says "Product Dimensions" but 90% of them are the same and I am assuming it's referring to the box they are shipped in. So far this is the closest thing I have found but am still not sure if they are compatible. Any help would be greatly appreciated as I already purchased and received a set of 33mm springs and now need to return/exchange them :-(

I spoke too soon. I just found this product spec sheet for progressive springs. However, there are four different 25mm models with similar spring lengths (483-486) but varying Spacers. How does the spacer come into play in all of this - if at all?

I bought the ones that I linked to in that thread. They arrived yesterday but I won't be installing them for a few weeks. I hope they fit.
