I finally found the tranmission cover and inspection plate for my '46. Are these items installed with slotted screws or bolts, etc? Also, did these items originally get installed with gaskets or are they just installed 'metal to metal' to keep water splashes to a minimum. My service manual was of no help.

Are these items normally painted the same color as the transmission? Is the front inspection plate left shiny metal or painted a different color? See pics for reference.
Thanks in advance fellow Stovebolters!
