i am planning to do a 5lug swap this summer, and i was thinking about getting a new rear end instead of only putting in axles. the reason i want todo this is because it would already be 5lug, and i could find one withgears that i want in it also.could i get a newer year rearend and swap it in? would there be any differences in the width of mine and the newer one? and around what year rearend should i get if i were to go that route?
