The easiest way to remove your upper ball joints is with a special socket (see picture below). There are three different sizes, for A, B and C-bodies.

A-body - 1.809"

1960-72 A bodies

B-body - 1 7/8"
Strangly enough there are also 1 59/64" sockets, which should fit the same ball joint?! My ball joint is a Moog K772 and the 1 7/8" fits like a glove...

73 and up A-body
63-78 B-body
70-74 E-body

C-body - 2 1/8"
Strangly enough there are also 2 9/64" sockets, which should fit the same ball joint?!

Mopar used three different upper ball joints on their RWD Torsion bar equipped cars from 1957-89.

1960-72 A bodies only used the small ball joint

1957-75 Imperials and 1974-78 big cars used the biggest joint (MOOG K778) It was also on light duty Dodge vans from 1971-03, 1972-93 2WD pickups as well as 1987-96 2WD Dakotas and most Vipers.

Everybody else used the middle size (MOOG K772) i.e. 1973+ Darts/Valiants, F-M-J bodies, most C bodies till 1973 and all B-R bodies

Je vais vous dire quelque chose de pas très catholique

Mais perso sur la coro on les à sorties a la presse hydraulique

Et même que le filetage était intact après coup (bon on a quand même mit de la Locythe histoire que ca tienne bien )
