I called Summit and looked at the TCI flexplate, the 157 tooth 50oz, but it said it was for a 2 piece rear seal. What can I use that wont cost alot???

Check CAT power products...they have cheap flexplates, balancer, etc. Good stuff.
You have a 1-pc. rear-main seal.

This is the one I have on my car, from TCI, part number 890-529610, for 157 tooth 10 1/2 bolt pattern 50oz. Is your bolt patter for the converter 10 1/2? or the 11 1/2 for the 164 tooth. This part number is from JEGS.

It is 10.5 for the 157 tooth. I am ordering the TCI from Summit today. Edgar do you have a shield in between your trans and block, is one needed? I know the T5 has that piece in between them and wasnt sure if its needed for a C4?

Yes you need it for the starter clearance, or it will be to deep in. If you can't find one, you need to modify one from a T5. See if you can find one in a Salvage yard or get one from Summit, it is a PA brand.
