TQ VB Flex Plate input shaft or ?
 

For my 06 48RE. Im looking at holding 450-500 hp. It is used mostly commuting 50 miles to work but I also tow 23k Trailers with it a few times a month and more. I also make a few runs down the local track every few months. The stock tranny is in good shape and only has 42k miles.
