These shocks were very common---just look at the long list......

maybe a connection for brakes??

I haven't looked at the numbers on my shocks. Are these the factory units? My front ones look ok, not leaking and the ride was good. I haven't looked at the back ones yet.

Brakes...? I went with stock on front but am researching upgrades for the rear. Ford medium duty truck (F800, CF6000, CF7000 etc.) rotors look like they would be close except that the hub pilot hole is 6.44, the MCC rotor measures ~6" (a sleve might solve this... and yes the wheels are stud piloted, but the rotor hub piloted); and the overall height is 6.02", MCC measures about 5.25 +/- depending on how much has been removed in surfacing. The "overall height" is what I see as the bigger hurdle, because it affects the offset of the rotor. This is a 15.38 inch diameter rotor. Would be a nice swap if it could work. Somebody has already converted one of my caliper brackets to fit the Ford dual-piston caliper, which is what led me to look at the Ford rotors (the rotors appear to be used in some other applications besides Ford as well). The previous owner two owners ago was doing something with these brakes. I'm trying to find him, but no luck yet. I've got a couple of things to finish up on my frontend and then I'm going to tackle the rears.

Those are not the same shocks that are on the front of my MCC. Haven't checked the numbers on the rear yet.
