    Heres the deal. I purchase this frame ('84 by the vin number). Removed the old frame side motor mounts (thought polys replace the whole thing). Threw the old ones away. Now every replacement mount I look at is too large. The mounts I pulled off were bolted in with 3 bolts. I hold the replacements up to the brackets and only two holes will line up at one time (2 top holes or 1 top and 1 bottom). Mounts for the 350 and 6.2 are the same, later models have 4 bolt holes. I have not tried the 6 cyl mounts yet. Any Ideas.

    Thanks in advance!!

    Are the back side of the mounts(part that touches the frame) flat? Are they countoured? I recall a while back that I kept getting motor mounts for a 88 truck instead of the ones I needed for the Blazer. Try going older or newer on the mounts and see what they look like.

    IIRC I had to go 3 years older for Autozone to get me what I needed.

    The 73-86 truck 73-91 blazer suburban mounts are 4 hole but only 3 are used, made that way for working on both sides.
    If you can not get the 3 to lign up you have the wrong mounts.
    I will get you picks later tonight for what you should have

    There is one difference in 2wd and 4wd models, the 2wd mounts sit a little lower, about 1/2 inch lower.

    Thanks. I got the right ones. I guess the ones I had were from a truck. Had only 3 mounting holes. The ones from autozone have 4 holes and line up right. They are about 1/2" shorter than the 3 hole mounts. Thanks for the help guys.

    ps. Had to get mounts for a 77 K5 4x4 w/350 motor.

    Cool.
    I am guessing you have a 6.2 L diesel right?
