Ok so it's pretty much completely different. I was starting to think it was just a few parts. I do want to get mine T&T and fluted bolt bodies. After seeing that SSS only charged $100 for the swap I was thinking there wasn't much into it but it looks like my thinking wasn't right. I do regret buying my predator after seeing the T&T and bolt swap is $240 I could have picked up an awesome rig and got it done for like $100 morethan I have into mine.
