Default Broken Flywheel - Advice Please

So I was backing out of my driveway last night and the car died, went to restart it and when I did I heard a loud snap and then grinding. Pushed it back in the driveway and jacked it up. First I thought the started took a crap, but after looking I notice the flywheel would rotate with only using my fingers. After looking some more I can tell that the outside end of the flywheel with the teeth is still bolted to the TC and rotates freely, and the other end is still bolted to the crankshaft with the connecting "spokes" in between sheared apart.

So I have to drop the trans... Been reading all the writeups on dropping it and whatnot. I pretty much know what I need to do and am just looking on some advice on some things:

Can anyone recommend a good flywheel? Im not trying to spend a ton but I figured I would upgrade since I'm in there. Or is a factory replacement sufficient? Car details in sig.

I figured I'll be able to just side the tranny back off the motor enough to access the flexplate and get the new one in there. Can anyone confirm this for me?

Any other things I should know or keep consious of?

Thanks Y'all!

EJ

You're more-than-likely going to have to drop the trans completely...it will be just as easy....if not easier....than trying to slide the trans back. I suggest buying a SFI unit...like ATI's. Do it once, and be done with it. Might as well replace the rear main seal while you're there. Hope this helps, and sorry to hear about your misfortune.

Gotcha. In sliding the trans back I was trying to avoid cutting my welded exhaust , but I guess doing so and just dropping it would open up alot of room and make it easier. I was planning on doing the rear main as well, forgot to mention, would be silly to have the opportunity and not relpace it. Thanks for the info, I will have to look into those

What do y'all think of TCI's? http://www.summitracing.com/parts/TCI-399173/?rtype=10

Thought all of the 4.8,5.3,5.7, 6.0 to 4l60 flexplates were the same 3 bolt to converter, 6 to crank. I was leaning towards the yank one that was mentioned in my thread in the transmission section.

Got the car back together. Went with the Yank ls1 flexplate. Here are some pics:




























In the end it wasn't near as hard as I thought, and was actually pretty easy and straightforward, only time consuming labeling bolts/cleaning stuff/etc. I actually ended up doing 100% of it solo, but it wasnt bad. I appreciate all the help and advice from you guys here on tech
