So, I've been working on collecting and then uploading to my Picasa account different parts diagrams for different year and style trucks. I've also got them for 1985 DLX Longbed 2LT as well. The links below will take you to the diagrams for the '87, and I've got them in a compressed zip, but it's about 3mb. So if you want that, then send me pm with your email and I'll send them out.

Tool/Engine/Fuel
Power Train/Chassis
Body
Electrical

These were all retrieved from toyotapartseast.com and so they will match up with their parts availability if you wanted to order parts.
