[SOLVED]making the roamer have body colored trim with my skin

i made a skin mod for the roamer, but for it to work i need the trim to be the same color as the skin, as of right now its black and being that body colored trim is a separate skin in the game i cant have them both together that. i was wondering what texture files and/ or what i should add to the jbeam and/ or my mod folder, also on a side note, is there a way to make the grand marshal's grill black instead of chrome?

 

Use "roamer_c_alt.dds", "roamer_d_alt.dds" and "roamer_s_alt.dds" in the material instead of "roamer_c.dds", "roamer_d.dds" and "roamer_s.dds".

 

thank you so much that was driving me insane
