I want to build/paint a GP-9 in The Rock bankruptcy blue scheme. The Rock Island GP-9's did not have dynamic braking. Is the dynamic brake 'bulge ' a separate piece on the WbB locos?? I have a WbB GP-9 that does not have the dynamic brake unit but I bought it that way....but all the photos of current models do have dynamic brakes.....so is it removable??? Thanks
