I have 69 Dart Swinger 340ci 4-speed built at Hamtramck,Mi. On the front of the K-frame is a(factory) Quarter size slug welded to it with a #no on it(06?) Why do some car I see have it and some don't,and what does it mean? I have also seen them on E & B body also. Thank for any Help with this Bob

Although I've never seen any documentation that explains it I have noticed that they are only on 340 cars. Up until recently I could not see anything unique about them, however after checking out a bunch of K-members comparing 340 to 318 cars (the 318 cars didn't have the slugs) I think I found out what they were for. The 340 units had a reinforcement piece which looks like a half of a large washer welded to the rear of the LCA pivot hole, likely due to the theory that 340 cars might be getting a bit more abuse. The slug was likely added and used as a quick identifier for workers when installing a K-member into 340 car since the reinforcement piece is not very obvious.

First pic here is a 340 and a 318 K-member (both are from 1971 Dusters)

Scott , you are comparing 71 duster K frames , the OP has a 69 Dart so do you really think it's a fair comparison ?

Are you talking about the welded on "coin"? It is a part number that relates to the k-frame number on the build sheet. Seen coins welded on top of other coins to change the part number as well.....probably a vendor re-work in this instance - like adding a skid plate etc. to an existing non-skid K

All holds true from what I've seen so far regardless of the year. The 71's are all I had handy pics of.

FJ5, none of the A-body units I've seen had any numbers stamped into them, just a bare steel round slug welded a few inches away from the assembly date code on the drivers side front face of the K-member as shown in my pic above..

Be interesting to know if you have one on a 69 A body , I've never seen a coin on anything older than 70 ...

I'll see if I can find some John, it's possible that they were only added after finding earlier failures with 68/69 340 cars so it may be that 68's and 69's (or early 69's?) never had them.

My 69 cuda 340 has a washer , not a slug, welded on mine. it also has the reinforcement around the LCA holes.

My 340 Duster has that slug also. So I went over and looked at my friends 69 340 Dart, it's there too. Must be a 340 thing.

Could you guys who have posted pics of K-members with slugs/washers please post the spd of your cars? Also the stamped in date code on the K-member and production plants if possible?

Thanks!
