So I installed a new lift on my 95 and have a nasty rear driveline vibration. I have stock NP231 (no sye) stock driveshaft and stock Dana 35. I know my pinion angles are off because of this. The rear diff is pointed at the t case because of the wedges in the new spring packs. I would like to do an sye and double Cardon shaft but don't have the cash right now. So here is my question- does a double Cardon shaft exist that doesn't require a sye? Any input on this matter would be great!
