FYI
I have a 51 EAB in my 40 Sedan. I bought it that way. Looked real good.
I went to pull the pan to change the gasket and the pan would not drop out. It would wedge between the front cross member and the flywheel. Check it before you bolt it in or you will at some time in the future be taking the complete engine out to change a gasket or crank packing.
