B&M 10239 flexplate (LA 360 to 904)

Title says all - looking for a B&M #10239 flexplate. The #10239 is used for when mating an externally balanced LA 360 (with a half-moon crevice in one side) with the small bolt pattern of a 122t 904 torque converter.

If someone on the forum has one (used is fine) and can beat the internet prices for a new one, I'm game.
