    What about a billet back plate for the 3V pump?

    Their claim is the old back plate flexes too much, causing the gears to break from binding up when the back plate hits the gears.

    im looking for the best of both worlds, I already have billet gears.

    Sounds like Ford B S if you ask me. The back plate on a pump is not that big to start with and is fairly thick and it has 7 screws holding it on, and you should not have that much crank end play for the crank to do it unless you have a thrust problem. I would almost say it would break the alum cover before flexing the back plate. Just checked the back plate on a Ford Cobra pump it's .178 find it hard that it would flex over such a small area. jmo

    obviously ford is confident in the redesign if they are using it on a 662 hp factory car. Back plate is the only difference between prior pumps that break the gears. I'm not saying its the best fix, just letting it be known of the new design. I'm running billet gears and will continue to do so. I did order a 2013 gt500 pump, which I plan to harvest the back plate only for my current pump with billet gears. It would be awesome if MMR would look at a separate back plate option.
