3. The method of making for a vehicle body top a head lining listing support having a tubular body portion of substantially T-cross section and attaching portions constituting flattened endwise extensions of said body portion, the stem of the T being channel-shaped and provided throughout its length at the side edges of the channel with substantially flat laterally projecting flanges, the transverse portion of the T being substantially flat and spanning the channel throughout its length, said transverse portion being pressed firmly in surface-to-surface relation against the lateral flanges aforesaid so that the transverse portion cooperates with the side edges of the channel to form a circumferentially closed tube and cooperates with the flanges to provide laminated webs at opposite sides of the tube, including the steps of first rolling a length of sheet metal to form the channel-shaped stem and lateral flanges and the transverse portion spanning said channel-shaped stem and to cause the transverse portion to be positioned in surface-to-surface relation against the lateral flanges to form the circumferentially closed tube and laminated webs aforesaid, then flattening the channel-shaped portion between and substantially into alignment with the lateral flanges at opposite ends of the body and to cause sec-- tions of the transverse portion at opposite ends of the body to be spread laterally apart, then piercing the flattened portions just mentioned between the laterally spaced sections of the transverse portion to provide holes for securing elements, and finally trimming the body and attaching portions to provide a smooth and neat structure.
