I would at a minimum, I would do a runout of the bushing bore (or the bushing itself). That would confirm if it is usable as is. As per the “Chevrolet Truck Shop Manual” the pilot bearing runout should not exceed .008” TIR (Total Indicator Reading). That is quite a large tolerance so it may not be so critical.
