Thinwall EMD 48" Dynamic Brake Fans pkg(2) -- For all Late GP/SD35s & Early GP/SD38, 39, 40 & SD45s

The primary characteristic of nearly all EMD hood units is the roof top fans. Now you can upgrade most models from the GP30 to the end of the Dash 2 series with these components, which feature ultra-thin top and mounting flanges, completely detailed hubs, motor supports and motor housing. The nickel silver grilles employ two-layer etching to replicate the prototype assemblies. Application data is for as-built units.
