Quick question about tremec TKO alum bellhousing

:OT: i just put my tko 600 with spec stage 3 in and it chatters real bad some say its a race clutch and thats how it is. anyone have any problems like this? sorry about jacking the thread.
 
With the 3550 in my 83, I drilled the ****TY VERY SMALL threads in the bellhousing for the trans, and tapped it to recieve the stock HUGE, and VERY STRONG trans bolts. Just had to drill it, tap it... and enlargen the holes in trans for the bigger, stronger stock bolts.

that could be, or maybe it is not aligned completely.
no its aligned correctly i spent 4 hours doing it different ways to make sure i got my measurements right. spec says i can swap the stage 3 disc to a stage 2 with out resurfacing the flywheel and using the stage 3 plate.
