I thought of an easier way to do this...
Changing too long, and now I not want to do other models from gta-iv...
How about the Steed from GTA IV made into a van?
Albany Manana 4-doors
Mammoth Patriot Limo
Take the GTA V Rumpo, put the Steed's front end on it and put the tail lights from the Rumpo Custom on it.
All three are based on late model Ford E-series vans... if you added those parts together, you'd have a nearly perfect late 90's Econoline.
I'll see what I can do!
