Whats involved? Want lsd and a gear change in my 2016 sxt - will existing half shafts work or do i need to replace those too? hubs? brakes? cradle? I assume the differential will just bolt in, but not sure about driveshaft etc - just would like to have all the needed parts here before i jump in.....alternative is just getting a 195mm open 3.06 out of an sxt+ stp ss or b-top car, but if im going to be in there anyway, i rather an lsd......and i dont see where a 195mm one is offered (in any ratio) thanks!
