    first of all i have an '88 k5 blazer stock 10 bolt rear. . .now onto the question.
    hey all. i searched before i went to the parts store and it appeared to me that the rear drive shaft u joints were 1310's. so i go to the local kragen and the guy tells me that it's not 1310 and that it could be one of like 8 different joints. so i am sitting there and he brings out some joints but they all have the external style retainer clips that are kind of "D" shaped. then he says maybe it's the 1350 and then says they are out of those. at this point i am pretty frustrated.
    so i go to a different kragen and the same thing happens. a few joints with the external style clips. finally i get one that has c-style clips that go on the inside. and i was comparing it to the one in the rear yoke and it looks like it is just barely too small (but it was dark and my eyes could have been decieving me.)
    so. . .can somebody please tell me what the proper size u-join that i need is? thanks in advance. /forums/images/graemlins/thumb.gif

    You should have a 10 bolt and if so it is a 1330.

    I was told that the later blazers have a "mechanics 3" u-joint size. It sounded funny but when I went to get my conversion u-joint for my 14BFF, I said I needed mech.3 on the driveline side and 1350 on the yoke and he knew what I was talking about. Try mechanics 3.

    Not true, the 10 bolt uses a Saginaw S44 joint.

    Proper part number is 2-3011 in a Neapco.

    2-1153 will convert you to a 14 bolt rear axle where a 1350 conversion is required.
