    I bought a Western Ultra Mount Poly plow from a 2005 Silverado 2500. Has anyone modified the 3/4 ton mounting brackets so they will fit on a 1999 Silverado 1500. Thanks

    Go on Western site. Frames may be the same.

    Frames are different

    The frames are different. The 3/4 ton bracket is bigger than the 1/2 ton bracket. Thanks

    I don't think it is worth it.

    You can commonly find one on ebay and turn around sell your's for the same money.

    Thanks guys, I found a used mount set from a 1/2 ton so now I am set. I did not get any bolts and nuts. Should I use grade 8 bolts, or what do you recommend. Thanks

    I think they come with grade 5. Use nylock nuts. You will be fine.

    Always use grade 5 bolts when installing plow frames with nylock nuts. Using grade 5 versus grade 8 allows the bolts to stretch or break before the frame of your vehicle. Good luck!

    I prefer stainless fasters, makes removal somewhat easier.

    On some mounts if the bolt is in shear they are usually a grade 5. If they are in tension (trying to pull the nut off) they are usually grade 8. At least thats what I found when looking up the part numbers to see what western speced out.
