Hoping to get my 4x4 again
 

I own a 1991 B2600i SE 4x4 for about 20 years now. When I first got it the incabin 4x4 actuator switch was missing so I removed under the hood the whole assembly of switches, relays, vacuum lines so I could have more engine working space. Years after that I got the 4x4 switch but can't find what I removed... sadly probably went along a cleanup. Wondering if any of the members here would have a "for parts" pickup and would be able to spear the assembly. I had try locally over junkyards and salvage places but hardly there is any of this pickup junked. Or if anybody could refer me to a salvage place with possibilities of having it. Thanks in advance.
