  We study the quasiparticle current in clean ferromagnetic Josephson
structures of the form $S_1/F_1/N/F_2/S_2$, where $S$, $F$, and $N$ denote
superconducting, ferromagnetic or normal layers respectively. Our focus is on
the structure of the conductance $G$ as a function of bias $V$, emphasizing the
subgap region. We use a fully self consistent numerical method, coupled to a
transfer matrix procedure to extract $G(V)$. We choose material parameters
appropriate to experimentally realized Co Cu Nb structures. We find a resonance
peak structure as a function of the intermediate layer thickness and of the
misalignement angle $\phi$ between $F$ layers. To understand this resonance
structure, we develop an approximate analytic method. For experimentally
relevant thicknesses, the conductance has multiple subgap peaks which oscillate
in position between low and critical bias positions. These oscillations occur
in both $\phi$ and the layer thicknesses. We compare our results with those
obtained for the spin valve structures $(F_1/N/F_2/S_2)$ and discuss the
implications of our results for the fabrication of spin Josephson devices.
