The rear seal old Massey part number was 187631M1 and the new Masseyt number is 744946. This seal is available from any Massey dealer. You may be able to take the part number to a NAPA store and have them match it up for you.
To change the seal, you will probably have to remove the rear cover that holds the PTO shaft from the rear end. You will need to drain the oil from the transmission/rear end - its all the same oil. A tip is to park the tractor on a down hill slope so you only have to remove part of the oil.
You can see a parts diagram by going to agcopartsbooks.com and clicking on "view books" in the "Guest" box. Enter Super 90 for model number and choose Massey Ferguson for brand. It will bring up a parts book for the tractor. Hope this helps.
