71DemonRON OP mopar Joined: Jan 2008 Posts: 484 PORT ALBERNI B.C. CANADA	I need a replacement K member for my 1971 Challenger. I picked up a decent one for $40.00 The guy said he got it from a local wrecker years ago, they told him it was from a 1974 Barracuda. It has 049M142 clearly stamped on the top side with a 7 also stamped on the top side, on the bottom it has what looks like 646141 ? It is a V8 k member with the 70 & up sway bar mounting holes. The only E-body that I can remember this wrecker having in the last 20 years is a 1971 challenger that had a 1970 grill. I checked the tech archives, no matches. Can anyone ID this k member ?

Drivers side I think but don't chisel it in stone. It was as if Ma Mopar had an idea but never implemented it because I have never seen anything bolted to them but they are only on the 74 E-bodies. Go figure.

The identification coins are spot welded to the K-frame and have a two digit number on them which is the last two digits of the K-member part number. For example, a 1971 E-Body K-frame is Chrysler part number #3583074. So the ID coin would be 74. Notice in the image below that the K-frame ID'd "74", fits 70-71 E-Body 383/440 w/skid plate and 71 B and E-Body 318/340/383/440 w/skid plate. The motor books will tell you that ALL 1966-to-1974 K-members will interchange. This is partly true as the K-members will bolt in, but the steering angle/pitch is what will bite you if you don't get the correct K-member for your application.

Out of about 10 K-frames I have only 2 have the coins. The angle has been measured to about 3.5 degrees. This was probably within the crappy tolerances the factory used in my opinion so it even if you get a 70 B in an E or vise verse it should be fine. The coupler will more than compensate for that. As long as it doesn't bind your OK.

But if you are running headers there may be issues. I'd check with TTI first about running E-body K frame in a 70 down B-body and vice versa.

After reading this thread via search, I came to realize the geometry might be off. It seems I have a 71 #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.. Last edited by hemi68charger; 09/07/16 04:47 PM.

Thanks guys... I'd prefer not to have geometry issues... I'm sure I can sell the one I have and pick up a proper "79" k-member.

I'd prefer not to have geometry issues... I'm sure I can sell the one I have and pick up a proper "79" k-member. the only geometry issue would be between the steering box and and steering column , I don't know what the angle is on a correct cK memeber and I don't know is there isa slight bind in the setup above , if it had something like a borgensen u jointo between the box and the column it would be fine. But I know that is not an option. You shouldn't have a hard time selling that one and getting the right K. Even if you can find a real nice 70 K without a skidplate you can always add the fresh repop skidplate, which won't be bashed in because the 70 plate is rather fragile in my opinion, and the repop coin. running up my post count some more .
