TIA.
So how are you connecting the 128 driveshaft to a 135 diff. 128’s are 4 bolts 135’s are a 50mm nut. That nut needs to be turned clockwise when you are looking backwards with your head under the driveshaft. For the 128 it’s simple by removing the 4 bolts.
If you need to get the nut off a 50mm harbor freight box works well. Shave about 1-2mm off to make it thinner.
