Thanks John,
Not sure what to have you measure. We've already confirmed the axle width from WMS to WMS is the same, and spring perch locations too.
I was more thinking looking at them side by side might notice any difference.
Again though, pretty sure I have posted the necessary information in the first post. Various pages from the parts catalog, is there a better source to reference?
What I really need help with, and or a second opinion on, is do these pages and part listings confirm that they're the same axle except stud length? I think so but I could also be wrong.
