Noticed you guys who are swapping engines do a lot of discussion on the rear diff setup. I got a 1990 190E 2.6 stock setup w/ a growl inthe rear diff that is getting worse. SHop I use found a new one in Jersey they will install for $1900. I found a used one for $350 I have to install. Anyone know what diff from what years I can use to replace my bad one? I was told a 1990 190E 2.6 could use a 1991 rear diff, but a 1992 will not work. Will older ones work? I really would like to get the posi rear diff from something to install. Please help.
