My frame has three holes in the top for mounting the motor mount brackets. I've seen both the fwd and rear used. I've used the front two but am going to run a fan shroud and was wondering if the fan would be too "deep" in the shroud if the front mounting holes are used. I've also heard that the rear hole is used for another year truck with the same frame. Any ideas on this?
