85turbo12a is on a distinguished road
trust me dude..i want to go..but it seems there are powerful forces at work trying to stop me...
first i get hit, then i get an odd and as of yet unidentified noise from the engine following being hit, and now i have a major driveline geometry problem that i didnt catch.

however it seems to me that the brunt of the issue lies in my grannies 8.8, the problem was probably there before when i put about 600 or so miles on it with the rotary shortly after DGRR2011 when i installed it, but was probably so borderline that it went largely unnoticed, it did have a previous high speed vibration, but not till around 130+, so i could have blamed it on many things never figuring the driveline would have a problem, since i ordered the rear to fit my application and parts, but NOW that i have changed things a little with this engine the problem has surfaced big time. the transmission is approximately 4 inches further back, and somewhere around 1.5in lower down. not a huge difference, but its non negotiable.

annoyingly i dont have a stock FB to measure on, BUT my trans is essentially pretty level in the car, and really it cannot move in any direction for any amount of worth while distance, but with that, the pinion gear is less then 1 inch below the tailshaft, BUT the issue is...the pinion points approx 3-4deg NORTH of parrallel, which is exactly opposite of where it needs to point...so its somewhere around 6-8deg off.
now i have but a few weeks and zero dollars to basically refabricate the rear end geometry and hope it solves it enough for my driveshaft to work, otherwise i will have to engineer and build a subframe in the middle of the car to house a carrier bearing for a 2 piece driveshaft assembly...not cheap, and not fun....

so with the damage from the impact along with it..im bout to call it a day and lick my wounds for a while
