Really simple and stupid question here from a new Model A owner. I am replacing the oil pan gasket on my 1931 cc pickup, but the "lower" flywheel inspection cover was not there when I bought the truck. I bought a replacement cover that I will install during the pan gasket change, but am unsure which way the half moon cover installs: with the lip forward towards the oil pan or with the lip backwards towards the transmission. I have seen photos online of the flywheel housing with a cover installed and there are pictures showing it both ways (these are ads selling used flywheel housings with the inspection plate attached). I just need to know which way it should go before I get it all tore apart and go to reassemble. Thanks ... Doug
