This is a suspension piece so a good prep is important to get effective weld penetration,
A good trick when tacking things like this is to lay the job in a piece of angle bar while tacking up it helps keep things aligned and means you don't have to earth the job..
I got in real tight and used plenty of heat to get good penetration, I’ve no way of rotating the bar while welding so I ended up doing 4 separate runs doing opposite sides to reduce distortion, I got a good strong weld but boy was it ugly. I dressed it back carefully on a grinding wheel and then dipped it in some gold paint just to stop the bare metal rusting (yes, I know the match is awful
but I’ll find something that matches better another time)
I ended the day by trying it “for a fit”. I will need to ensure I can set it level once the truck is built up so I‘ll probably drill another couple of pairs of holes in it so I can adjust the height if needed, I’m not sure whether to weld or bolt the chassis bracket in place (any suggestions?), but that’s a job for another day
