hey guys, i was talking to a guy at my work, and he said that he has a tremec 3350 that he is willing to sell pretty cheap...he said 300 bucks with bell housing and everything, only thing the syncro's are shot, anyone know how much it would cost to get those bad boys replaced? is it worth buying it cheap and getting it rebuilt or just dishin out the $1300 or whatever it is for a new one? thanks
