Okay so i finally finished building my motor and since i took so freggin long i ended up just buying random parts for the trans. I picked up the j's racing 5.1 final drive and the cusco 1.5 lsd. This is the first import motor i have built and it wasnt easy. I have never gone beyond the bell housing for the transmission and am wondering if its a good idea or not to attempt this install. How hard is it? and about how much am i looking at spending if pro's do it?

Thanks in advance
