What are the differences between 1120173 and 1102268 as far as judging? I have the drawings and they look the same except the rear lower flange on the 173 is .4" thick and the 268 is .5" thick after a drawing change date of 11/6/62.
Anyone know if/when the flange thickness change was made for the 268?
