Happy to help, credit goes to charlief1 (http://www.ihadav8.com/forum/index.php?topic=3268.0) and a great post on the other board (https://www.turbobuick.com/threads/suspension-and-steering-rebuild-for-beginners.376776/).  Just passing it along.

(If you're ever interested in rebuilding your front suspension/steering, seriously save those two links.  I'm a complete novice and redid my entire front end a few winters ago, in my garage with minimal tools.)

Sorry to hear when he'd passed.  He was a wealth of information and always very helpful with my dumb questions.
