Well finding pictures is tough. I remember trying to find pics or an Air Conditioning Eliminator for my mustang. (pics on actually how it mounted) took me about a month to actually find pics. I would find the exact model of engine and then search, and then find some toyota forums, you would easily get a correct answer in a hurry.
Just Thought of Something
Go to
www.cardomain.com I found some trucks of around the same year on there but no engine pics, maybe you can find someone that owns a similar truck and they can take and email you some pics.
