If they are steel I might be able to use a magnet to fasten them next to the triangle on the trunk underside

They are steel. But surprisingly light considering the task they are to perform. A magnet should work well, and it shouldn't have to be a very strong one, either.

I know I'm going to regret asking this, but what is a "Jack Plug Add-On"?

I'm guessing it's a piece of steel that slides into the jack holes, so you can use a regular floor jack to lift the car. Is that correct TheDon?

If it is as you describe, then I have one already. See attached pics. However, I had this one made by a machine shop in San Jose, CA when I lived there. It’s made of hardened stainless steel. The stainless steel ball at the end is a standard size, and allows smooth movement of the piece in the lifting cup of the hydraulic jack. This baby works great! If you make one, it absolutely *must* be tempered after manufacture.

I assume you're asking about the 'Jack Lift Thingie'... well, that's my unofficial name for it. Unfortunately, there is no cost. I happen to be fortunate enough to have done a bunch of professional business with a machine shop in the SF Bay Area, so they gave me a ‘free sample’ of their work, based upon my specifications. I supplied the drawing; they did the work at no charge. You know how it goes.

It's made from stainless steel and the ball is standard - a well-knowledgeable machine shop can find the ball in their supply catalogs. Cost will vary wildly based upon the shop's capabilities and geography. To reduce cost, I suppose it could be made out of standard steel, but it absolutely *must* be heat-treated. My first iteration bent (!) the first time I used it. They made an exact duplicate and had it heat treated. I only own one and have used it many times.

While I no longer have the drawing I made, I could easily re-create it, if anyone is interested. Not sure if that's what you were hoping for. By the way, do you happen to have the MB part number for the 'official' version?

Ahhh... Now I see. The name makes sense now. Thanks!

If you can get these made and reasonably priced, I would absolutely purchase a set. I've been thinking about what it would take to have a shop here make them, but I wasn't sure about how strong they would have to be - maybe a forging?

The adapters and screw jacks described in the 107 MB shop manual look absolutely safe, but are probably no longer made or four figures a set.

The piece is ridiculously easy to make, utilizing only two raw, stock components - a 7-inch piece of 1" diameter SST bar stock and a 2" diameter SST ball. The bar stock is lathed down on the one end to fit into the jack hole. The SST ball is then welded onto the opposite end.

The unit is now complete, except for tempering. While I do not know the specifics of the tempering process, I do know it was considered "standard" and nothing special was needed. That's it!

I chose stainless steel to keep rusting and abrasion to a minimum, as well as added strength. The piece could be made out of forged iron, I suppose, but I have no experience as to whether it would work or not. As I mentioned in previous posts, my first iteration bent when using it the first time - lifting one jack point of an R129. It did not break, but I was concerned about snapping. Obviously, the sheer force to snap it could be deadly - literally - as the ball-end goes flying.

For safety liability concerns, I would prefer not to manufacture them. I have no problem placing the design in the public domain as long as no profit was generated from the finished product. And to be honest, I'm not sure what the cost would be. Any machine shop with average experience with stainless steel welding/manufacture can make this thing very easily.

Folks, by the way, where might I obtain that emergency triangle that folks mention, that perhaps would fit on the underside of my 1983 300D's trunk lid?
Thanks so much in advance!
