The clunking is gone but I can still feel a little drive line vibration if I pull away hard in first. Otherwise smooth. Nothing too concerning, but I might take a closer look at my rear suspension bushings when I get a chance. None of them have very many miles on them.
I might be asking a little much of a 30 year old car at this point, but I can't think of a good reason for that initial vibration, which was defiantly causing the clunking when I had the softer bushings in.
