Side members AA-5015, AA-5016 and No. 2 cross member AA-5025 have been redesigned.
Side members, which were used on trucks on which the service brake cross shaft brackets were mounted on the inside of the side member, are no longer supplied for service.
No. 2 cross members, which were used on trucks equipped with dual high or old style emergency brake cross shafts, are no longer supplied for service.
If you should receive calls for one of these side or cross members, supply the present de- sign side member or No. 2 cross member and drill them in accordance with sketches shown in Figs. 870 and 871
