Back to this fun stuff. Found out my rear driveshaft was bent. Had a new one made. That took care of about 75% of my vibes. Right around 62-68 I still get an intermediate vibe. To me, I feel it in the wheel and under my feet near the pedals...so I think its in the front end.

Swapped another set ofwheels/tires and no change. The front has new shocks and steering stabilizer. All the balljoints, wheel bearings, and tie rod ends are tight. I do not have a front driveshaft in it plus I have manual locking hubs so I know its not the front axle. The last pieces I havent touched are the leaf springs/bushings. I'm positive they are original. They are dry rotted, cracked, and at least one of the front leaf spring bushings is split. I'm thinking that worn bushings could be causing the rest. Could this be the problem??
