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.
