Superbird K-member

[hemi68charger]

Hello All..

Been doing a lot of little stuff on components of the Superbird. Lately, a friend and I worked on sealing up the suspension parts, differential and k-member with good epoxy primer. We did however notice something about the kmember which makes us believe it was swapped out at some time...

Question: Are ALL Superbirds equipped with the k-member with the ID tag of "79"? And, are they all welded to the driver's side? Mine isn't.. I believe the last digit is "0" on mine. The first digit has a big ole attachment weld over it....

The Superbird ended its road days with a 426 Hemi...  The k-member does have a skid plate, so that's proper........ a regular 383 1970 k-member wouldn't have a skid plate if I recall............

Back in the day, I saw original 1970 cars with a 440-6 that had no skid plate, and once owned a 440 70 GTX with a plate.

AB - 79 is correct for a non-Hemi Bird.

Thanks Jim,
Guess I need to be on the look out of a '70 Bbody 440 k-member then......

[hemi68charger]

Weird though.. The k-member is a '70... and it has a skid plate............

Troy,if the k member is a 70 and has a plate,I sure wouldn't lose sleep over it but thats just me !!

True... I could always find a "79" tag... But, you do know I've been hanging out with a particular person a whole lot lately.....  

OH yeah.. Saw that dual-point distributor you sent him... Nice !!! I tried to explain to him it was really mine and you sent it to him by mistake....... lol

I'll get a picture of the tag...

Is the fourth digit a "0"? The fifth digit is a shift code.

Not sure what you mean Jim ( date code? and if so, where is it? )

.......... I'm taking it is a '70 based on the holes for the sway bar bushing bracket...

On my 69 K frame those numbers are stamped in the center front above the lip where the rad support brace attaches.  Most are very faint to read, especially if someone went at them harsh with a sandblaster.

I buddy of mine did some research.. Seems you know him Bill..

But, it appears my k-member is from a '71 440 HP car, part#3583100. This would validate the apparent stamp of "00" on the tag........  Maybe I can "troy-trade" this much rarer k-member for a "79" '70 b-body..  

I came to realize the geometry might be off ? It seems I have a #3583100 k-member since it appears I have a "00" on the tag stamped on the k-member. I know the proper k-member is #3466479, with a "79" on the welded tag. Can this 71 k-member be used? My buddy has the ability to reweld a reproduction ID tag on my current k-member. Or, I can try to trade it for a proper '70 k-member. After all, mine is more rare..

Hi Troy,
          I have an E-body k frame on my Daytona convertible. The only difference is the steering box brackets.  I had to shim the box so the steering column would line up.          WINGNUT

Thanks Pete...

I'll try to find something.. Would rather not have to do that.....

There will be a date....sometimes it is very hard to find if it is stamped lightly and/or there is a lot of material on the k-frame.

So does every K member get the round "coin" with the last two of the part number welded on?

[maxwellwedge]

No they don't.
It seems to be more prevalent starting in the 70 model year.

I have seen coins welded over other coins underneath to change a k-frame # to some other configuration. This was done by the company making frames. I'm guessing they may have needed more with say -  a skid plate that particular day and modified an already made one.

[66FBCharger]

Maxwellwedge,
Is there a date this process (welding coins on the k member) was started?
The reason I ask is, I have a '70 440 6 bbl. road runner. It is an early car (8/23/69). There is no coin on the k member. It does have a skid plate.

[Hemi Runner]

Very interesting. I was assuming these K-members were 70 units because of the sway bar mounts, but maybe not?

[Hemi Runner]

The date code on the first appears to be 3179 on the first one. The second one looks to be 6230 unless I'm reading that upside down. Any guesses?

[Mopar John]

How about 025 9?

[Hemi Runner]

That's probably it.

....

If the tag is a "90", that is a '70 B-body 318/383 k-member, part number 2962090.. if it is a "06", I'm not sure.... I'll have to look in my parts book...

[70gtx440dana]

I have seen several of the #90 K frames with the #79 coin welded on top of them. I have a 70 Charger with the 90 coin and a skid plate and a date code that aligns with my SOP date.
I believe the 79 coin was welded on it at one time and either fell off or was removed.
I just sold a 70 K member with the 79 tag welded over another tag. The coin welded over top....could have easily been popped off with a screw driver or similar.

I suspect the OP has an original #90 K frame that has lost or never had the 79 coin attached.    You should be able to confirm by the date stamped in the front.

Hey everyone..
Went and checked out the k-member today... It has a stamp of 3289 2 on it..... So, according to this, this is Nov. 24th 1969.. I would guess that is appropriate for a Nov. 30th build date for my Superbird.. Soo,, I guess my Superbird got the incorrect coin on the k-member..... hard to see, but it is 3289....
