I took a picture and posted it for you. You can find it here:

http://pg.photos.yahoo.com/ph/bjdcfrey/album?.dir=/b15bre2&.src=ph It was taken by stuffing the camera in corner, where the driver's side firewall meets the inner fenderwell, looking under the carb at the exhaust pipe just before it connects to the manifold. (There's no way a person could stick their head in there from the top...probably not from the bottom either!) It gives an idea of what is connected to where, including the spring. Like Bill/Red58 said, there is a tab off of the pan. The hose that you see in front of the linkage is for the oil filter.
If you can't access the photos, please let me know. I can email the picture(s) directly if you like.
Hope this helps!
Bill
