I'm swapping a GM 5.3 with a built Th350 into my Sn95 mustang.

I just bought the TCI Ls1/Th350 converter and it says it will bolt directly up to the Ls1 flexplate. Will it also bolt to the 5.3 flexplate. Ive heard the 5.3 plate is curved...

Do i need to swap to a stock 5.7 LS1 flexplate?

 

Any insight?

 

I imagine they are the same but... I have my 02 stock flexplate for $20 should you need it.

 

Ill keep that in mind if i need it. Thanks!
