none of the angles were changed before this vibration and then the vibration just shows up. gears and trans have been in the car for 3 months and this problem showed up 2 weeks ago

Listen to AdderMk2 he knows what he is talking about, Hard launches can sometimes change the angle for you. And remember if you won't pay heed to advise given don't ask for help if you know more than everyone else.

i am taking the advice just throwing differents senerios out there. what should i look for in the mounts? i pulled the driveshaft out again 2day and there were scars on the yoke. not from the seal. i could run my finger nail down the yoke and it would get caught in the groves.

then your bushing ISNT fine..

looks to me like you need to repalce both the bushing AND yoke at this point

yeah im going to try that i thought the bushing was fine because the yoke didn;t have any play but something isn;t right because the yoke shouldn't have groves
