Default Driveline shake?

Before I start shimming and moving things I just want to be sure this is what Im experiencing since its new to me.

A month or so ago I lowered the front end of my 67 after rebuilding the front end with new control arm bushings and such. It started to shake pretty good at like 50 mph.

Since then I lowered the rear 2" with 2 degree sloped blocks. Then I took it to get it aligned. The shake is better, but it still starts to rattle fairly hard once its up around 70 MPH.

Is that most likely a driveline angle issue? The rear is a tick too low now so Im probably going go to a 1.5 or 1" block. So ill probably adjust it then.

If anything I thought my angles were too shallow, so Im surprised its shaking like it is. I was hoping the alignment would fix it.
