We present analyses of the young, Crab-like supernova remnants (SNRs) G54.1+0.3 and 3C58 in the X-ray and radio wavelength regions using public data from the Chandra X-Ray Observatory and the Very Large Array. By overlaying the X-ray and radio images, we discover similar anomalous radio quiet point sources in each object that are slightly offset from the X-ray pulsar ( 5'' and 10' for G54.1+0.3 and 3C58 respectively). The radio quiet sources are likely not coincident with the X-ray pulsars due to the unrealistically large kick velocities that the pulsars would have to possess. To explain this radio offset, we discuss simple physical models, several of which appear promising, but all of which have significant weaknesses.
