Looking For A Ax-15 Or 5Spd Southwest Michigan

[Sp0okyone]

My transmission (BA10/5) is going out. I have a 87 Chief 4x4 5spd I6 4.0L I am restoring. If you could help me find a new used transmission to replace it with that would be the $#!&! Preferably the Ax-15 but Ill take anything that works right now.
