Is it possible to swap a 400 4x4 rear differential for 300 4x4 on a 1995. Bought a pair of 1995 bayou 400 4x4. One is complete, runs and plan on flipping it. It also came with a "parts" atv that is practically complete minus the rear differential. Seems to be difficult to find a complete bolt in rear diff for this year. Any ideas on what will fit in its place? Thanks!
