NORS Federal Mogul engine rod bearing set for Flathead Ford V8 1938 - 1945 at .060/SEMI; like Ford Part Number 81A-6211. Fit 221 and 239 with 91A and 21A connecting rods, 1.998" STD journals or later crankshafts ground or offset ground to the smaller journal size -.060" nominal.  These shells actually measure .1430-.1435" thick so need to be machined for -.060, or some other lesser undersize, or grind the crank to ~-.067 to use as is. These bearings are not flanged.
