I am seeking schematics, exploded diagrams or other technical data regarding the changes made under the AMC Pacer's hood in order to make the heater and a/c housings clear the V8 engine in later model years.  Are there any other specific forums or data areas I should be visiting, or who offers publications or data sheets for such use?

Thank you for your time.  

try lhis link....
http://www.autozone.com/shopping/repairGuide.htm     they have some stuff....  

Some very nice stuff in there to peruse and gain understanding from.  Thank you very much.

I'm still amazed at all the room there; the first time I popped the hood, I thought I was looking at a Fox-body for all the space I had to work with.  

If you still need the Pacer service manual diagrams go to my website and send me an e-mail. I can scan them in from a service manual and send to you.
