A lower ball joint was bad in my tubular A-arms, the ball joint looks like Chrysler but so far my parts house can't find the right one.They were purchased from Rodparts Warehouse & they said Chrysler K car which they aren't. Please look at the pictures and help me ID this part.
Pictures are below.
Approx. dimensions are as follows:
Lengths;
OAL- 4.18"
Cup length-1.62"
Taper length-1.44"
Thread length-1.12"

Diameters:
Cup @ threads-1.84"
Top of taper-.72"
Bottom of taper-.62"
Threads-.56"

Most k cars were pressed in.......This pic is out of a 72 challenger
Chrysler used this type for many years,And I dont know how many diffrent measurements there was.hope this helps ..good luck

Try Moog K772 ball joint for a Chrysler..Some apps include 65-73 dodge and chrysler and 80 monaco . (that would mean KRUZR's 72 challenger is the same also ).I think it is the Chrysler upper ball joint that they use in both arms on a MII.

I have one of those at the shop that I can measure iffin ya want me to.

later, mikey

Kruzer & Mike,Thanks for the replies! Mike I'd like you to check the dimensions if you have time. We've been looking for a lower ball joint, I didn't know they used the upper in both applications.
Thanks again, Fred

As all of the critical measurements are within .010", I'd say you are good to go with that K772.

Now, when I said that the uppers and lowers were the same, I was referring to the ones that I have seen installed in the upper AND lower aftermarket tubular arms, from several different mfgrs. That does not mean some company has not done it differently, I have just not seen it.

So I will clarify, the MII stock arms do not use screw in type.

(I know if I didn't say something about that, in 2 years someone will join the board and ressurect this thread just to call me on that point.)

HTH,

Mikey
