4x4 won't engage on 1995 Toyota T100

I put my t100 on jack stands, put the manual trans into h4.
back right wheel turns, nothing in the front wheels. I remove the vacuum lines to the front differential, at the differential, and the front wheels now turn. Bad vacuum solenoids or ADD? Where can I buy these parts? I replaced the vacuum lines weeks prior.

I'm having the same problem out of my 4WD T100. The part that engages the front differential goes by a totally different name then they give you. It took me a bit, but I found the part that you need. Here's the information from AutoZone:
"Motormite/Transfer Case Switch"
