1970 camaro firebird control arms
 

Can someone school me on the 70 arms? I’ve been told these are one year only. Also, want to know how to decode the stampings. Are they date coded? Any info appreciated.

Control Arms are not judged for any date stampings at the Camaro Nationals LEGENDS Category.
Ive never read anything explaining control arm stampings !!!!!!!!

70' Camaro control Arms are NOT one year only , but I cant remember what year the bushing size changed for larger bolts..........

I do have these NOS Upper Control Arms .....................

The pictures shown here are of a NOS over the counter upper control arm. Control arms do have date codes and are stamped in the arm. 1970 camaro arms have 1970 only ball joints different from 71 and up. Uppers and lower ball joints.The NOS arms do not have the correct nuts and ball joints in them and wouldn't be accepted in judging. If i may ask are you restoring a 1970 camaro?

I’m working on 70 Trans Am, March build.

I sent you a message. Please reach out to me from the message?

My upper has what I think is a date code. It is C1 70 and can be seen on the top at the 9 o’clock position. This makes sense for my car which is an early April 70 build.
The lowers have codes also stamped, but I haven’t made sense out of them some trail off the edge of the steel.

Didn’t see message. Sent one to you.

For some reason our messages are not going through. Im not receiving any and none are going out.

Adding some reference pics reinforces the dating. These came off of a 05B Camaro. E0 makes sense not sure on the next two. Maybe shifts? I’m curious on the other stampings as well. Appear to be a D on one,A on the other and a 0 on both.
If anyone has similar pics and a build date to go with them I’d like to see more examples.
