So it appears part# 0504-613 is the rear knuckles for all year 1000's. I cross referenced the knuckle parts with that of a 2006. It uses the same axle, axle bearing, bushings, and bolt hardware to mount up to the A-arms. So is it safe to assume these knuckles would work on my 2006?
This knuckle is the key. If it would mate up to my A-arms then it would seem that I could purchase all the necessary hardware for a 1000 to fit my '06 (knuckles, hubs, rotors, brake lines, and calipers). Then it seems it wouldn't be too hard to make the conversion other than the expense.
Any chance we can get some dimensions from you 1000 owners? Maybe the width of the two locations where the A-arms mount? Maybe the length between these two mounting points as well? Just figured I could compare these dimensions to my current knuckles....
