I've been putting some miles on the car. Not as many as I'd like though.

My son and I went to the local Cars and Coffee the other week, which is always fun. (I robbed some photos off the C&C Facebook page)

I still have a driveline vibration that's bugging me. The front and rear driveline operating angles are both exactly 2.9* and the overall operating angle is .02*. Even after I was able to get these angles, I still have a vibration at around 2000 rpms, then it goes away until about 4500 rpms. Above 4500 rpms, it's a fairly significant vibration. The engine revs smooth though, in neutral, to the limiter so I'm confident it's not the source.

I took my driveshaft and had the balance checked yesterday- all good. It has new Spicer U-joints. I have sufficient yoke engagement on the trans output shaft. I spoke with Ridetech this morning to see if they had any suggestions and he said with my pinion angles and a good driveshaft, he wasn't sure of where to go next.

Someone mentioned driveline compound angles, which is one thing I haven't checked. The Tremec app measures the angles on a horizontal plane, but I haven't checked them on a vertical plane. At a glance, it "looks" pretty straight. Anyone have any tips on checking compound driveline angles?

Also, I've grabbed the driveshaft right in front of the rear pinion and tried to shake it and there's very little/if any play. I was told when I bought it that the pinion and axle bearings had been replaced. But, I have noticed a very slight pinion seal leak because the bottom of the length of the rear end pumpkin is slightly damp with fluid.

Any ideas would be greatly appreciated.
