My 79 frame has factory holes - does your year have them?

    I'm looking at making a generic bushing mount using some existing frame holes - My 79 has them, I'm kinda curious what other years may have them in the same place. The largest holes are elongated and sit 22" - 23" forward of the rear spring mount in the center of the frame. There are a few smaller ones surrounding it. Here are some pics -

    I just measured on the '88 frame out in the garage. It has the oval hole in the pic. From the center of the forward spring eye bolt to the center of the oval hole is 22 inches. /forums/images/graemlins/thumb.gif

    Thank you to everyone who checked. I'm pleased to see that at least all the half cabs look like they have it, I'm curious what it might have been for. I have brake lines behind mine but gently shifted them to one side for my mount. Getting a 75 and 76 might definately draw the line on where it starts. I guess I'll have to make a full wrap around mount for the rest of them.

    Car carriers and such have "T" hooks that go in those holes and turn to tie them down. Those are points for that or that the factory used to tie the frame on something. You'll find those oval holes at the front and rear of most frames for this. /forums/images/graemlins/thumb.gif

    <font color="green"> I beleve that those holes are designed as points that can be measured between in order to see if the frame is straight. </font>

    I've got a '75 K5 and a '90 Sub, so I'll try to remember to do a check and get a measurement for you tomorrow before the snow starts for the week. /forums/images/graemlins/eek.gif
