I used to have a link for the skid plate at TRDParts4U but the link is dead now unfortunately. You can use the Tacoma skid plate for the 99-02 bumpers but you just have to fab up some extender brackets if you want it to sit flush. RonMAIDEN has done this on his truck.
skid plate is nice but cheapest i can find it 100$+ !
sounds about right for a skidplate. actually seems cheap.
