In the Moog book you can cross most of the Gm numbers over to a Moog number. Some examples:
GM #3827036 = Moog 6000 This was the softest spring from the factory on a 409 car. Free height 17.63 spring rate 270 lbs.
GM #3827038 = Moog 6084 This was a stiff spring, free height 15.3" and spring rate of 370 lbs.
GM #3827034 = Moog 662A Soft spring not used on 409 cars
GM #3827039 = Moog 658A Stiff spring not used on 409 cars
GM #3827033 = Moog 6304 Soft spring not used on 409 cars

so the 6304's are right but the 601's show as a cargo spring?

Thanks by the way for everyone who looked up part#'s for me, appreciate it...

I used to put cargo coils on all my Station wagons.. It raised them 1 inch, and they NEVER bottomed out
BYGDDY said
Oct 26, 2009
well it looks like the # is for rear cargo coils which is fine, i will likely screw em all up anyways when i cut a coil out of each but i bet it won't sag or bounce anymore...!

you are CUTTING the new coils?? the "new"coils?

From what I know about Cargo Coils I don't think cutting them will work well.
BYGDDY said
Oct 27, 2009
Yup, sure i will regret it but yup.....is the end result of cutting cargo's vs normal coils much different? And im talking one coil, not a bunch...
4SPEED427 said
Oct 27, 2009
From what I know, the design of Cargo Coils is such that they need the spring intact to function correctly. I think a normal spring has the same rate regardless of whether it's cut in half or not.
I am by no means an expert on springs and someone more informed may well correct me.

Oct 27, 2009
I think Carl is correct cargo coils react according to the weight on them (as in different loads in a wagon) Is this car one of those"tuner cars" lowered down??

Grabbed of the web,
WHAT is a Varible (Progressive) Rate Cargo Coil? Varible rate springs deflect at different amounts per inch. An example would be: 200 lbs. = 1 inch deflection, 600 lbs. = 2 inch deflection, 1000 lbs. = 3 inch deflection, and so on. Varible coils have a soft initial spring rate and a much firmer spring rate to handle more weight, decrease sway, and improve handling.
I think with a progressive (cargo) spring for the 70' B rear, you'll be limited to cutting from the top or tightly wound load end. And that should be just fine, as it has a completly circular index. The bottom or control arm end of a cargo coil on these cars, is widely wound and terminates with a progressively tighter pigtail. This tail gets indexed around a raised stamped portion of the spring clamp. It cannot be cut here.
I'd think one coil out of the tightly wound end should not drastically affect the rate, capacity or overall feel.

Thanks very much, that was the plan was to cut ONE coil out of the tightly wound area and no, it most certainly isn't a "slammed tuner car" I just am not a big fan of the stance and would like the whole car to sit down a inch/ inch and a half. Thanks again for looking that up, it confirms what i thought and stops me from worrying about the simple things....

I wouldn't be surprised that with taking one coil out of a new cargo spring, the car may still sit higher than with the old sagging fixed rate springs. Good luck, and let us know how it goes, take some measurements to make a comparison if you can.
Here's a shot of the cargo coils I got out of my parts car, they looked so new I just went with em'. I have absolutely no idea how my 69' rag will eventually sit when the time comes! We'll see.
