1. A seal plate for a gas turbine engine comprising: an annular wall provided about an axis extending in an axial direction, the annular wall extending between first and second ends that are radially spaced from one another in a radial direction with respect to the axis, the first end includes an axially extending pilot, the second end included an axially extending flange and an adjacent annular seal seat, the wall including a portion between the first and second ends extending substantially in the axial direction and configured to permit the second end to move axially relative to the first end in response to thermal growths;
wherein the portion includes first, second and third portions, wherein the first portion is transverse to the second portion and the second portion is transverse to the third portion, the second portion is arranged between the first and second ends and extends substantially in the axial direction and is configured to permit the second end to in the axial direction relative to the first end in response to thermal growth, wherein the third portion extends from the second portion to the flange on the second end, the flange extends in the axial direction, and the third portion extends radially away from the second portion and is canted in the axial direction toward the first end, and the first portion extends to the first end.
