I've read with fascination the discussion on the Flyte Sweep deck lids. According to my Hollanders Interchange manuals, they differentiate "w/ tire panel" and "w/o tire panel" (with and without). Here's the Chrysler part #'s listed for the Imperials:: 1877584 w/o tire panel '60 1877585 w/ tire panel '60, '62-'63 2188835 w/ tire panel, '61 2188938 w/o tire panel '61 2253363 w/o tire panel '62 2425297 w/o tire panel '63 If we cull that down to just the ones WITH the tire panel: 1877585 w/ tire panel '60, '62-'63 2188835 w/ tire panel, '61 It appears that the '61 is the oddball. At least part # wise. Who knows....maybe they just changed part #'s for the '61 and they are all really the same.
