While I do have the 1971 Chrysler/Plymouth Body and Chassis Service Manuals (and CD), the area for the "A" body heater box (non A/C) is quite vague in its illustrations. Does anyone have a better illustrated break down of this assembly? I sure would appreciate it. to who ever has it in their archives. And as always, thank you very much.

I have the parts manual on CD, but I don't know how to save just a single page. When I select a page and go to save, it shows the whole manual. If anyone knows how to do that, I'll send you a copy or post it here.

Hope this helps.

There ya go, good job Snoopy.

Thank you Snoopy, that will work real fine.
I think I'm OK with getting this torn down and put back together (I'm making one good one out of two), but it doesn't hurt to have a good reference sheet in front of you.
Thanks to all that responded. You kept the ball rolling.
