I am more familiar with the task force trucks, but I think you need to consider the whole front end as a single part. cab-fenders-rad support-hood. if the rear mounts are easily felxible, te center mount is fairly non flexibe, and the front mount is flexible, then what you really have is a see-saw effect. I will be using the stock mounts from a newer style truck under all contact points of the cab and rad support. that way they all have the same ability to flex as a unit. the box is solidly bolted and seperate from the cab so that part is straight forward. my frame, however, is not a stock frame and is fully boxed and cross membered fairly stiffly along the ladder as it goes along. my floor is also not a stock floor so I will just say consider how one body part needs to interact with the other body parts. the old stock mounts will likely be fine as long as the rest of the system isn't modified for strength and flexibility (or non flexibility).
