What years upper and lower control arms interchange?

[Wizard]

What years of upper and lower control arms and torsion bars can you interchange/use on dodge and plymouth b body cars? 2 door and 4 door the same? 6 and 8 cylinder the same?

Thnks,

Bar thickness varies. Numbers are on the back of the bars for ID. Upper arms are the same 62-74. E body 70-74 will interchange also. Bars fit from 62-74.

Actually, it is 1962 to 1972. In 1973, the entire suspension changed.

Yup mistype. Should be 62-72 B body and all E body 70-74 interchange. There are slight sway bar differences on the lower arms.

Okay, I appreciate it. Have some 65 upper arms from a Belvedere II I am going to use on a 68 satellite. What is the easiest way to identify a B body lower control arm from a A body. I have a bunch of loose ones off of cars and dont know what they came off of

A body are stamped VL. B body are stamped PD or RW. The stamping letters are on the front below the rebound bumper. All are stamped RF or LF as well.

Question for yaz please if having installed firm-feel box and modified front end alignment: Did you find any need to change out or interchange the arms, steering linkage, etc. for this? Due to problems with clearance I'm going to have to disassemble the linkage and likely replace the torsion bars as one has been damaged by the tie rod rubbing against it. The problem has also caused the center link to play the violin on my left TTI header. Thanks.
