Those look damn close. I bought roadster ones and they were too tall. I had to shape them down using a sanding disk on a grinder. They bolt through which I like but if I were to do it again I'd buy the ones you bought.
In other suspension news, the 521 tie rod assemblies, right and left, are a direct fit for the 320. Mine just arrived from Rock Auto and they are a perfect match.
Front shocks on the other hand were a little bit of a pain. Monroe shocks 32113 are a good fit but the bottom is too wide to fit the bottom shock mounts on the chassis. I took a grinder to the shocks and shaved them down to fit.
