Thanks for the help!
I totally agree that an option that includes an adjustable ride height is the way to go. With my luck, just changing springs would result in a ride height I wasn't happy with.
My understanding is that springs with a higher rating than stock are also shorter than stock. If I'm correct it would be a real crap shoot to know what the ride height would end up being with just a spring change. I guess it could even end up being lower than what I already have.
I drove the car about 50 miles today (first time it's been driven since the late 1980's) and then got it on a level driveway. Here's how it looks now....
When measured at the top of the rocker, it's got a very slight downhill rake (to the front). As a perfectionist
I would still like it a shade higher in the back (1/2-1"), but I'm going to try to live with it as is.
Thanks again for your input and help!
