Nothing like waiting to the last second to put the rig back together. Finally thought I had everything to finish putting the axle back in last night and one of the last things was putting the calipers back on. Did the passenger side and then went to do the drivers side....picked up the wedge and little allen head bolt that retains the caliper on the D60 but couldn't find the spring thingy anywhere that goes between the wedge and caliper

Not sure what happened to it. Fortunately Advance Auto has one in stock....at it shows it on the webpage so went ahead and bought it.
