weird shake with acceleration

[Dirty325ix]

The car is a 89 325ix and it has recently developed a weird shaking issue when accelerating quickly from 3k-5k...especially in 2nd and 3rd gear..when I drive the car smothley it seems to have no issues
Does this sound like CV issue? I know my boots are torn
Could this be a driveshaft issue? I didn't install that centering pin I just did front drive shaft straight to diff
Or could this be related to my 5 speed swap I did 1500 miles ago..when all these parts were last taken off?

Yeah, that's kind of important.

you want that centering pin. why wouldn't you have put it back in?

my first suspect would have been a guibo either way.

I had two rear guibos so it would not fit up front and I heard of a few success storys....but that's good news as long as it doesn't sound like my clutch then it should be cheap.....Isn't a thicker flex disk up front a good thing is there someway I can find a centering pin from another car or do I just buy the right guibo
