fellow All-Trac driver! It's a fun wagon, not the fastest thing around, but pretty reliable.
As for the shop manuals, you should be able to order them new, although used ones do sometimes pop up on ebay. Recently there was a set (shop manual + electrical wiring manual) of both on ebay for under $40 I believe.
Newer is pricey. It seems this is the page for 1992 Corollas, but the All-Trac repair manual isn't listed. I don't know... make sure before you buy one, being that they cost so much!

I only see the All-Trac specific repair manual listed under 1988:

At least the electrical manual is much cheaper!
