Hey Guys,

I have a friend with a 70 340 Challenger that is signed by Rock on the rear wheelhouse. Does anyone have any info on the history of Rock signed cars? I know he signed a lot of cars.

Thanks!
Randy

my memory only remembers signed B-bodys (Coronet/Belvedere) so he must have been at the Lynch Road plant for a while

It's only found on 1970 E bodies from Hamtramck as far as I know.
I have owned quite a few myself and have personally seen hundreds .
We used to comment on the 'Rock' signature way back 25 years ago .
I am sure lots of research has been attempted, and even a magazine article or two has been written about it, but I don't think anybody has gotton to the bottom of that story (?) as to who Rock was .

I think "Rock" is the DB Cooper of the Mopar world.

My car had Rock on inner fender wells. E body built 4 30 70 .I don't think this s a persons name .I think its simple nobody would spend time to just do something they were not told to do. I think it just stands for Rear Operators Checked. That they rolled the rear windows up and down and they worked. Just my opinion. We will never know unless the guy comes forward to tell us. Inspection marks make more sense than a worker wanting to sign his work of art

1970 Hemi Cuda, SPD is December 15th 1969

Rock, Dickie, Mickey, etc., etc, it was very common for people to sign these cars in different places.

Thanks for the info Guys!

my T/A has Rock on the inner fender, believe it's only Hamtramck built cars.

Barry, Are we sure that it was signed or maybe info to install Rocker trim. I have Rock signed on left side and R on right side. 70 cuda with rockers fish trim.
What do we think?

ROCK shows up on a whole lotta cars without rocker trim.

Has he signed both Dodges and Plymouths?

He signed Dodges & Plymouths, A & E-bodies.

Ok, got it thanks Bob

Were any wheelhouses on convertibles signed?

My 70 Cuda convertible 340-4 speed had ROCK here...

Was that a common practice to switch lines between makes and body styles?

to help determine if this is a single individual .....

any been seen other than HAMTRAMCK?
any been seen other than HAMTRAMCK assembly line #1? (EN1 on fender tag) the smaller line at the plant)

all year long? SPDs?

Line #1 at HAMTRAMCK 1970 model year produced Barracudas, Valiants (incl. Dusters), Challengers & maybe Darts (BW, any Darts on LINE #1?)

any of the above, all lined up bumper-to-bumper in any order

I have a 71 Demon SPD 603 from line #1. It is a cool car with good options and colors V8 powered with 904.
