1. A link for a heavy duty truck comprising: an elongated U-shaped channel made from steel and having a pair of end portions; said channel having a top wall, a pair of side walls and a pair of arcuate end surfaces; said channel having a longitudinally extending axis spaced from said top and side walls of said channel; a pair of end brackets for said channel; each end bracket made from a sheet metal stamping to provide a body of generally rectangular configuration at one end thereof which forms a receptacle for the corresponding end portion of said channel; means for securing said end-brackets to said channel; each end bracket having a pair of laterally spaced apart side walls connected by a top wall; and a pair of aligned openings in the side walls of each end bracket, said openings being located on an axis perpendicular to said longitudinally extending axis. 2. The link as defined in claim 1 wherein the top wall of each end bracket includes a portion which engages the corresponding end portion of said channel and an inclined ramp interposed in said top wall between the front and rear portions thereof. 3. The link as defined in claim 1 wherein the opposite edges of the side walls of each end bracket are provided with overlapping flanges which are secured together. 4. The link as defined in claim 1 wherein said end brackets are welded to said channel along the side walls and top wall of said end brackets. 5. The link defined in claim 1 wherein each end bracket has a pair of elongated bracket slots provided in the corresponding side walls, said channel having at the non-connected longitudinal edges of said side walls outwardly extending and longitudinally extending flanges of generally arcuate configuration which extend from one end of the channel to the other end, with the flanges at the end portions of the channel extending into the bracket slots provided in the side walls of the end brackets. 6. The link defined in claim 5 wherein the changes of said channel side walls near the ends thereof are provided with channel slots, said end brackets having on the side walls thereof locking nubs which are received in said channel slots to assist in securing said end brackets to said channel. 7. The link defined in claim 1 wherein said channel is made from a high strength steel. 8. The link defined in claim 7 wherein said high strength steel is in the range of from 80 ksi to 140 ksi. 9. The link defined in claim 1 wherein said sheet metal body is made from sheet metal is in the range of from 30 ksi to 60 ksi. 10. The link as defined in claim 4 wherein said welding is gas welding. 11. The link defined in claim 1 wherein said end brackets may be used with channels of varying lengths to serve as a stabilizer link from the cab to the frame of the truck. 12. An end bracket for a link comprising a unitary body made from a sheet metal stamping; said body having a pair of spaced apart side walls, a top wall and a pair of overlapping flanges forming a bottom wall; said body being open at the front and back; said body having a longitudinal axis extending through the ends of said body spaced between said side walls and said top wall; the front end of said body being open and of generally rectangular configuration; said side walls having a pair of aligned circular bearing openings which are located on an axis perpendicular to said longitudinal axis; portions of said side walls near said overlapping flanges being provided with elongated bracket slots; said side walls adjacent the front end of said body and said bracket slots being provided with a pair of locking nubs. 13. The end bracket defined in claim 12 wherein said sheet metal is in the range from 30 ksi to 60 ksi. 14. The end bracket defined in claim 12 wherein the upper edges of said side walls are curved starting at a place above the axis of said circular bearing openings and extending in a direction away from said bracket slots.
