Thanks, Count -- I did see that site, and went back to it one last time. I chose and used Moog #6308, purchased through NAPA #277-1984 (for expediency). They are a wonderful solution for this particular application. My ride height is perfect (IMHO), and the spring rate is ideal (even if it's a Chevy spec) -- not harsh or stiff, just right for the era, as this is primarily an ice cream car for the kids. The car is now a delight to drive, and will be much more this summer.
I will post a link to a pic, when I have a decent one ...
