I have a 98 Sentra SE with a blown up differential(flung a few teeth on the spider gears). I had a friend find me a tranny but it is out of a 2000 Sentra with an SR20. Will it fit in our B-14???? It appears to be cheaper for me to find a used tranny with a LSD then to buy one and put it in my transmission. Any help would be greatly appreciated!!!!!
