There are a couple in the factory manual you could start with:

Given Jeff's comment, AutoAtlanta sells the factory manual on CD for around $50, then you could probably print it to whatever size you need for the specific diagram, as with the above cross-section.

If you copy it as a jpeg as Jeff did, onto a plain CD, then take it to a local blueprint/repro shop & have them print it to large format, if your home printer won't go big enough. Just make sure to crop to only the diagram without a copyright notice, because they'll not do it with it showing, even though that copyright is probably expired by now. You can do the same thing by scanning a hard copy page with the diagram, or using a Kinko's copy which goes up to 11x17.

THANKS tom , and jeff....Your Ideas may be the only solution.
