Fabbed up some front sway bar mounts(PIC'S) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I spent the last few days fabbing up some front sway bar mounts for my 71 Blazer.

As some know our 4x4 Blazers and 4x4 trucks did not come with a front sway bar.

A front sway bar from a late 70's-80's Blazer can be used.Just find the doner truck and take the bar,mounting bushings and the spring plates(they are a direct bolt on.)
Here's the spring plates

After making some templates out of cardboard I started fabbing up the mounts.

I used 2x4 box tube .120 wall thickness.I also used 1/4" flat stock in places as well.

After the initial cuts I marked where the sway bar would bolt to the mount.
I then welded in two nuts on the inside of the boxed tube.

After a little more cuttiing and rough fitting of the pieces,I tack welded the pieces together and made a final test fit.

Once I was satisfied with the fit I welded up all the seams and ground my welds smooth.

I repeated the process for the other mount.

After these pic's were taken I ended up welding nuts to the mounts and painted the mounts black.

Here's how it all turned out.
In these pic's I didn't have the mounts permanently fastened yet.But they ARE in their final position.

Here's the beefy sway bar.

ALL the pic's I took while making these mounts can be seen HERE

I'll give Steve Chin credit as I based my mounts on his basic design.I just modified the design slightly and beefed them up a little.

I welcome any comments,questions or critiques.

so i am guessing the mount for the sway bar is different on the 4x4's compared to the 2 wheel drives?

In the second to last pic you can see the bolt that is used to fasten the end of the sway bar to the threaded spring plate.

Ya it's different from the 2wd sway bar.

I reinstalled the sway bar yesterday and took a drive.

It REALLY tightend up the handleing.It feels like you get "pulled" through corners now

I also cleaned up the sway bar.Took about 6 hrs of sanding and polishing but I now have "blingin" front sway bar.
I clearc oated it and reinstalled the urethane bushings.Turned out o.k.

Here it is before

And here it is after.
