Well i just bought this car and got a decent deal on it and my buddy has a wrecked 06 with 5spd he said i could have everything to change mine to a 5 spd but he wants 150 for the rear end as i just wanted it to throw under mine since it has the 3.31 in it is it worth 150 to have 3.55's on the auto until i possibly swap in the 5spd i also believe i have a 3.90 in my notchback and it is not in drivable condition but not sure if i should waste the time pulling it or just buy new and with an auto this is still gonna be my dd too so any thoughts would be great
