Can I use my flywheel off of my T-56 with the Turbo 400, or do I need to get an auto cars flexplate? Also, what is a flexplate and where can I get one kind of cheap if that's what I need. Please let me know asap, cuz the car is goin in this weekend, and if I need to get parts, I need to try and get 'em quick! Thanks in advance for any help!

You will need a flexplate for a automatic. You can get a stock one from the GM Dealer, but I would recommend you call SDPC and get one they sell them for less.
Or you can call MADMAN Racing, they have SFI Flexplates for the TH400/LS1 now. I am running a stock flexplate but my next one will be the MADMAN's.

Also, do you know if anybody has a premade driveshaft for the Turbo 400 in an LS1? Or do I have to have it measured and then custom done? I'd rather just buy one premade, so I don't have to wait.

Even though you have a little play in the size of a driveshaft when giving the maker your length I still wouldn't risk going by someone elses measurements. Luckily when I was finished with my TH400 install I did my measurements and drove 5 miles to Broward Powertrain, they made me a steel drive shaft that can handle up to 1300 hp in 2 hours.
Check your local city for any companies that can make you a driveshaft. If you want a lightweight one like a carbon fiber, you will have to order it. And for $700 for a CF DS, I would do the measurement my self to make sure it 100% right.
