Being a GP, you likely don't need them in the position to hold the gear selector bracket. I think that was primarily the H/C/G bodies in the 00+ years. You can put them in any position you would like. I put them up on top where it's easy to deal with them.
I also replace those four on the bottom with regular case bolts (I have billions of spares) and never worry about that torx junk. There is no need for torx to be on the bottom that i can find.
