i got 03 gt special edition no supercharger runnig fine except for some tranny issue, picked up a 99 gtp accidented, thinking of swapping the motor and trany from gtp to my gt, looking to spĂȘnd about 1000.00 for some extra mods, gt has nothing done to it yet, any ideas and what to expect from them. also what will have to be changed to make it work, the dash reflecting off the windshield is something i would like to swap.

thanks in advance
