Yeah Dan, I only replaced the fronts. You're right, I should do the rears anyway. I'll get that going right away.

Just did new shocks. That's in another thread. I did that as part of this problem. I had converted to tube shocks years ago but the solution I came up with placed the shock in near vertical position. Reading from this site said it would be better to angle forward. I am now mimicking 47-55 shock mounts. It does ride better but had no effect on the vibration.
