I have the GKN with the latter rear cover and the oil fill is not easy to get at, the early GKN the fill is in the side which is better, other than that I believe they are the same.
From what I have followed on here, GKN is fine but spares for fefurb are drying up and the BTR is better long term option.
Someone is selling BTR diffs on PH classified with brakets as a conversion for GKN diff cars. Circa £900

Some else has mentioned that there is now a coversion kit available from one of the Specalists for a about £250ish.
I would recommend doing this as I did a coversion myself which was a lot of work (even with the body off at the time).
You can either move the speedo pickup to the diff output or leave it on the input (either works) but I found getting the trigger wheel in was be very tricky and in the end removed it and used the output (as the sensor bracket cameo with the diff I got).
All that I had to do was lengthen the wires to the sensor.
I also kept the original drive shafts after checking the suspension range for any issues with the new diff.
