    What are you running for a gutting edge?
    If you are using a cutting edge larger than 6 inches the plow will trip easier.
    The springs will over compress and will have to be changed when a 8 or 9 in cutting edge has been used.

    Even a good fabricator would take a lot of work to add trip springs to a Fisher.

    I have seen people use spacers, but first I would trry replacing the springs.

    By the way all my Fishers even my new one were tripping in the snow, so were the Meyers and Westerns.

    That is the reason you are tripping them to easy.
    Bigger is not always better!
    Fisher factory cutting edges for the 9 ft hd plows are only 1/2 by 6 for that reason.
    By installing a 5/8 by 8 you have changed the whole geometry of the plow design therefor it now trips easier and the angle to the ground has also changed to were it will not scrape as well. a 5/8 by 8 edge weighs twice as much as the Fisher edge's. You have also added weight to the front end of your truck putting more strain on the front end, the plows hyd. system, lift arm and chain.

    Sorry I was only going by what you told us in this previous thread.
    The A frames on the MM HD plow did have a week area.
    New replacement Fisher part # 8627 A frames have a extended reinforcement inside the channel. When set up so the A frame, and truck is on level ground with the plow lowered, make sure the A frame is perpendicular to the ground. Then you should not have a problem unless something else is amiss.
