OK, so I have an 88 Eagle my son is driving has a mega engine vibration issue. I did the Nutter bypass

This is NOT a driveline issue as it occurs at idle and when I am driving down the road I can throw it in idle and rev it and the vibration increases greatly, so it is not related to wheel speed. Seems to hit around 2000 RPM. Everything is stock except for the Nutter bypass. It starts and idles fabulously!
I know what it feels like, but I am hoping it is something else... your opinions are valued... please don't say to check the ujoints... remember it happens when sitting still at idle. I had previously replaced the Dist, Rotor, Wires and plugs. Checked firing order twice and the engine times nicely after the bypass. Vacuum advance working great.
I am pulling the plugs 2mrw to see if a carbon chunk has flattened out a plug electrode. I can hope, right?
Have a great weekend
