The problem is the cab was repaired incorrectly as the gap between rocker & floor edge should be 7/16"-1/2"
So your floor is either protruding 3/16'-1/4" or the rocker top edge is pulled in that far. You might try crimping the top edge of the rocker lip slightly to gain any additional clearance needed to install them.
