I got a carbed LS-1 and I am putting it in my 1977 vette.

My question is the LS-1 came out of a auto vette, what do I need to put it into a Manual car (TKO-600) I know I need a different bellhousing that I ordered.

What fly wheel should I go with, I noticed there are 2 different ones different amount of teeth?
What are good clutches?
