Another possibility a Dakota rebuilder could offer would be to take the factory OEM natural gas parts off early 1990s Magnum 5.2 V8 Ram 15 passenger vans and transplant them plus a new certified large capacity high pressure natural gas cylinder onto early 1990s Dakotas with Magnum 408 ci V8s with MPI intake manifolds.

Natural gas 408 ci V8 Dakotas would have a low cost per mile driven,
even lower $ per per mile than a 40 MPG diesel Dakota.
