unknown vibration

I have a 76 el camino. I've replaced ALL the steering componets. Have brand new rear tires and very good front tires. I've got a fresh alignment. ?Car rode brand new for a couple of weeks. It just started shuddering (vibrating) when it is under a light load. Leaving the light it does not shudder. However, after accelerating halfway to the shift point (th 350) car begins to shudder. I baby this car and don't launch hard. I'm 69 years old and don't do stupid stuff. I go from point a to point b. Does anyone have any idea what may be causing the vibration? Thanks in advance for your input.

How many miles on it and what service have you had done on the transmission?

Sounds like you threw a wheel weight.

imo, vibration only under light load rules out the out of balance wheels...just make sure the lug nuts are tight. Sounds driveline related to me. trans, driveshaft, diff.
