Falcon transmission output shaft seal

[SlowMod406]

Last minute issue with a bad output shaft seal on our Falcon late model transmission. The winters part # 7257 is not in stock anyplace local. Is there a known GM seal that will work? thanks

Same seal as a powerglide.

Same seal as a powerglide.

Correct,a direct copy from the bert tailshaft.
