Need motor mounts for 71 Firebird LS swap with TKO 600

[7firebird1]

Hello all! I am in need of a set of motor mounts for my 71 Firebird that I am dropping an LS engine in with a TKO 600. Not sure if I want it in the standard location or forward or set back. The car is going to be more of a mild pro touring car. I have also heard that the tunnel needs modified with the installation of the 6 speed. Anyone out there in G Land have any suggestions? Thanks in advance!!
