So, i picked this thing up of craigslist for $50, figured why not, could be of use for a future project. Anyways, It's a C103.
Here's what I know: '84 axle, out of a UPS truck. Disc brakes, 10 lug bolt pattern (similar to what is running on a F450's these days). 5.29:1 ratio.
Spring perches are 40" apart, but could be moved easily. WMS~WMS = 67".
Really I want to know if the 10 lug hubs can be swapped out for the Rockwell 6 lug hubs, specifically the ones off a Rockwell F106. Or maybe I could get the hubs machined to work with that 6 lug pattern? But there isn't much material to work with, seein as how there is already 10 holes drilled in 'em.
I know there isn't a lot of Rockwell info on this site, but I figured it's worth a shot.
