Hey all I need input. 49 1/2 ton,old lines 1/4"..rear axle 3/16". New set from Inline Tube, lines on rear axle are 3/16" also BUT the treaded ends are to small for the brass blocks. Checked my other trucks,none match that thread size. I let the old girl sit all winter,(no heat) in the garage. I sure would like to see her roll now. Is it possible they put the wrong ends on? I know some had 1/4" rear lines from what I have read. Im frustrated.
