The ep specific bodies are to narrow for a converted nitro, you will need one these bodies......mugen mbx7 eco Jconcepts body.....or FTW TLR 2.0e Exabyte body......or any body that was made for a 2.0e , I like the mugen one as it is a nice fit once trimmed rite to fit and has an aggressive forward cab aerodynamics look( it looks like it means business on the track haha) and have used the FTW before but is a little on the thin side.
Hope that helps...
