As mrfury68 points out above —- and he is clearly one of the smartest people on this site…
The 1965 - 1973 “ C “ body LOWER BALL JOINT ** ASSEMBLY **
Is a one piece unit , approximately 12 “ Long —- and the
Ball Joint part/ component is part of the 1 - piece Complete Assembly — ONLY —-
And it fits 1965 , 1966 - 1968 w / Drum Brakes , and 1969 - 1973 —- ALL —- with Drum and Disc Brakes….ONLY …….
The 1966 - 1968 “ C “ Body with the BUDD System DISC BRAKES —- uses a much larger unit , different contour to wrap around the Four Piston Caliper , and is twice the weight and bolt in points for the security of “ not falling out “ …..
The K719 MOOG ( Obsolete / Discontinued) , which Mevotech
( Chineseum ) “ stole “ their number , and call it an MK719 or their cheaper version , a GK719 , from 1963 — through — 2025
Fits — ONLY — some of the models of the “ B “ and “ E “ bodies where they used a THREADED LOWER BALL JOINT — LOWER BALL JOINT — in 1973 ONLY….
While it “ looks “ like an Upper Ball Joint , the shaft is much thicker than the conventional Upper Ball Joints…..
I have taken the time to 100 % inform you —- in a college professor’s dialog —- and not a 1st grade teacher —- so , if anyone doesn’t understand now —- read it twice….
Yours, Craig…..
