The early amazon (and 1800) have a clip held held by one bolt (threaded into the body) that holds the sway bar. The later ones have two bolts. The larger sway bars that IPD sells, come with a clip for the two bolt set up and says to weld in a nut for the earlier body. Most installation I have seen, they simply drill through frame member and install a longer bolt.

I'm a pretty good welder but debating how to tackle this. Has anyone done this and been happy with it? Did you drill a hole from the top (big enough to get the nozzle in and weld the nut to the bottom, internal surface of that member)? Did you use a forstner bit to cut a plug out of the bottom surface, drill the smaller hole for the mounting bolt, weld the nut on the back side of the plug and then weld the cut out (with nut on the back) back into the member from the underside???

Chris;

I had the same situation on the Snow Weasel...so I'll add "Burner Welding's" solution to the other good ideas from other posters...see: http://www.sw-em.com/nagging%20clunk.htm

Cheers

PS. If you have any crusty Fuseblocks, I could use some again...please contact me per e-mail. Tnx

Hello,

There are several ways to get threads for the forward sway bar bracket bolts for an early 122/1800.

The easiest way is to drill a 3/8" hole in the frame using the 2 hole sway bar bracket as a guide to determine where to drill the hole.

You then open the existing slot in the frame with a file or die grinder so that a flanged 3/8" nut with a serrated bottom face can be inserted into the frame.

You then push the flanged nut over the drilled hole and then get the bolt started by threading into the nut.

If after getting the bolt started, the nut starts to turn, just pull down on the bolt while turning which should cause the serrations on the under side of the flange to dig into the inside of the frame to prevent the nut from turning.

Once you have enough tension on the bolt, the nut should be able to be tighten to its proper torque.

We have used this technique in several areas of many cars with broken weld nuts in confined areas.

You can also thread a piece of plate that can fit inside the frame by using the same basic technique.

Or you can weld a nut over a hole in a piece of plate and then install into the frame.

If you do not mind the initial difficulty of getting the bolt started, you do not need to weld it in.

Otherwise drill a couple of holes in the frame next to the hole in the frame for the sway bar bracket hole and then weld the plate to the frame through the extra holes.

I have thought about this before purchasing the bar, and here is what I was going to do. Drill the extra hole the size so that a nut will go through. Buy some thin flat stock (12GA) and drill the two holes in it. Then weld a nut above one of the holes. Attach the plate to the frame, by using one bolt through the hole and into old threaded nut. Make sure it is square and then weld the whole plate to the frame. Do this for both sides.

But if you dont have to weld it, I would proabably try Phil's idea.

I've done a few by drilling all the way through the frame member and then using a long 3/8" bolt and nylock nut, with a thick washer on the upper end. Seems perfectly sturdy to me...
