Cpp upper tubular control arm hitting

Trying to fit these tubular A arms which came in classic industry kit for 68 dart, including 11 in disc setup, the front tube is hitting on a small support bracket welded to bushing housing and frame rail. Is it ok to trim and put plating elsewhere..1/8 in plate? You can see piece I trimmed and tubular arm still hits but don't know how low to trim. Any ideas y'all is appreciated0506171901.jpg 0506171902.jpg
