Does anyone know what were the correct heater and a/c hose sizea for a 1972 T/A. I believe I read somewhere the a/c hose was a ribbed design but don't know for sure. I have an assembly manual and it does not tell me the hose or clamp size. It give the part number for the clamp but not the size. Any thoughts would be appreciate as well as any pictures of an original/unrestored a/c routing. Many thanks

Frank,
Here is a pic of my restored, but not to original, 72 base model Bird's system. I used more effective crimp collars to replace the hose clamps and the latest barrier style ac hose to keep that expensive R12 inside. Les

The heater hose sizes are 3/4" for the one to the head and 5/8" for the one to the front of the block. The correct hose clamps are the post type in same two sizes.

Thanks Tim
 . I use Eastwood underhood black rattle cans to spot paint components using shop rags and cardboard to stop overspray. The ac labels are new repops. Then I use spray Pledge on old t-shirts to remove dust and give a matte gloss to the underhood parts including the hoses. I also use Pledge on the tires: spray on, wipe off. I haven't heard anything from Steve O and the only contact info that I have is his wife's. Apparently, he meant it when he said "adios". Les

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
