Welding now done. Although only one trailing arm bracket needed replacing , As the axle had to be dropped, took the opportunity to have the welder strengthen all the poss weak brackets ie fir top and bottom trailing arms and panhard rod and spring supports.You can get the parts from Arctic but my welder said just as easy and cheaper to fabricate. All epoxied and undercoated ready for corrosion treatment now. Also has him give the underside a good look over and as I thought just surface rust. So ready fir anti corrosion treatment now when it warms up. Thanks fir all the advice.
