Those are modified welded parts , not sure who or where , but I’m sure the have been welded on at one time . Mind you the welds are not welds but just tacks , this is scary scary stuff . Do not modify any thing on steering or brakes unless , you know what you are doing or you have a qualified person modify it for you . Questionable work here spells pain and dollars to me . I hate to say it but I really do not think , this was sold this way from Speedway , or should I say finished for sale this way . Someone played Mater Builder and created a death trap . You are one lucky man .
