I know there were 3.5 v8 in later w111 coupes, but I'm wondering if the 3.5 is a bolt-in on earlier w111. Was the low grill required to fit the 3.5? If so, did the fenders and trans tunnel change to fit the larger 3.5? And if so, would the manual trans drivetrain 3.5 from my 1972 350sl fit without modification?
