    I have a '79 K20 p/u, and without taking my axle apart ,are all 6lug 1/2 ton 10 bolt fronts 28 spline and 8 lug 3/4 ton 10 bolts 30 spline, or does it vary by year?

    Thanks for the reply
    Yeah according to the CK5 Blazer specifications page they switched over to 30 spline in '89.

    No . They changed at a certain year , although a few may of been made early , or carried over late depending on who you speak too .

    It wasn't the amount of lugs either . 8 lug don't mean chit , its a 10 bolt .

    Search and shall find the year break .

    A 79 would have 28 spline axles. The year break is roughly 88.

    so could I find 8 lug 28s and they would slide right in with no other mods? and what about the rear is it the same way?

    the axleshaft from a 6 lug 28 spline 10 bolt front is identical to an axleshaft from a 8 lug 28 spline front.

    There is no rear 8 lug 10 bolts, only 6 lug. A 6 lug 28 spline 10 bolt axleshaft will fit either side or any 6 lug 28 spline 10bolt axle.
