I haven't been following your woes, but have you ever checked your driveline angles?

 

Thanks. I will be having all of that done whenever i get the poly mount and it in an actual shop where a trained professional will do it. Im getting all of my new yokes together for the swap as soon as i get back to my hometown after finals. Why the diddly **** would the GM engineers put an Beer Can aluminum driveshaft behind a V8 that makes a fair amount of torque? I know its less rotating mass but ****!!!! I know that my old dshaft was fatigued because i had laid over the spider gears in my open carrier with 3.42s. Between the burnouts, hard launches and whatnot, i think the whole thing was just on its way out.
