Yeah, I'm still around. Had a bad fall and have been busy with other interests, but, as Mark Twain put it, "News of my death has been greatly exaggerated."
Was away from the dragracing forums and would not have known that the free space I was given on a commercial site was gone...and the site itself...if I hadn't started to receive phone calls. Didn't realize so many of you used those spreadsheets! So, the site URL given below (a new site of my own) includes some of the spreadsheets.
I also answer the question: If you were able to start a new project, which rear suspension would you use? Would it be 4link? Ladder? 3link? My answer might surprise you.
