Questions on tranny and cables for 3s swap, lots of pics including engine bay remodeling Options

[celicaracer18]

Ok my first question is about the shifter cables needed for a 3sgte swap into a ST

i have always been told that i can't use the ST cables, and i have to use GT cables
well i have GT cables but the plastic coating is coming off and they are not in good shape

i was camparing the ST and GT cables but the only difference i can see is the bracket, so could i use my ST Cables

here are some pics side by side










second ? is is this a MR2 LSD tranny








here is my new engine bay, still in the works






lastly where can i get anew one of these
