First I am new here, Hello. I have been into all types of cars and trucks. Right now I has been Hotrods and Diesels. I have a 37 chevy pu and a 97 Dodge Diesel pu

I am very interested in MD Diesels, but still do not know enough. So, looking for help.

My choices are
1976 300d auto trans (may need head gasket)

1979 240d trans?

1982 240d looks to be manual trans

1983 300d trans?

any help would be greatly appreciated
