Rock Auto has those and other brands if you want to get the numbers or buy them.
I use Monroe shocks, they shock okay.

Start with Rockauto to see what Moog springs they have. (I bought mine there, as well as other Moog parts.)

Then look up the technical specs on them here:

Make yourself a little chart on which ones to choose from.

If you have the assy manual, you can find out the specs of the springs that are on your car currently and what you wish to have now. If you have manual tranny, the rates for the rear could be higher, possibly to prevent wheel hop...
I found that (for the 350 anyway) the Moog spring rates are higher than stock.
I chose the HD rear springs for lady and they are almost a little too firm, though the ride is well controlled. The rear Moog STD's have the same rate as the factory W29 rears (auto trans), and the moog HD rears are close to the factory HD manual tranny ones.

As for rear shocks, I got Bilsteins (F4B460929H0) and painted them grey like original ones. They were 60 bucks each at shockwarehouse.com with free shipping. Ride is pretty good so far - her rear seems to out perform her front now. The thread on the rear rebuild is called "lady's rear enhancements".
Front shock # is F4BE3D150H0 but I have not ordered them yet. I will do the front suspension in another year or so.

I am confused. I am trying to restore the ride height on my 69 Cutlass convertible, so I am looking to replace my rear springs. Carquest gives me a part number with GREATLY different numbers than what is referenced here. They are quoting a 6313, which according to the table has a rating of 385. Compared to the 120 standard and 160 HD, this seems crazy. Any help?
