Less than 90 degrees to airflow reduces efficiency, Turning vanes as found =
in large air handlers in buildings are required.

When building cars I went to the NAPA store nearby and looked in their pict=
ure books for any shape you might have in mind. Then they can look up that =
picture by part number. I used GM evaps for oil coolers with dash AN-12 mal=
e fittings. Submerge all but the top few fins in water and weld away. No fe=
ar of damage. Junk yards usually pile them up for scrap from older cars. Id=
eal for us.=C2=A0 =C2=A0U-pick it yards are good because you can check if p=
ressure is still in the system. Probably a good unit.
Never mention "AIR PLANE" when buying things.
