    Will this work on a 1986 k5 blazer and will it work with disc brakes on the back?

    Asked by: Brown
    The Jegs 555-631018 booster kit is universal fit--modifications will be necessary and only works on disc/drum brakes.

    would this bolt up to a 1981 chevrolet malibu

    Asked by: mrmalibu
    The Jegs 555-631018 booster assembly is not a direct fit for an '81 Malibu. Fabrication may be necessary.
