muncie four speed correct TANGED gaskets

[john302]

Does anyone know were to purchased the true correct gaskets for a muncie trans. The gaskets  are the ones betwwen the main case and tail housing.The original gaskets have a tang on the edge that sticks out.All of the rebuilders are using the replacement gasket without the tang and are incorrect.  Thanks John

You have to use an original GM gasket set.  Think if I remember the number is 3917763.
