Realized that the R31 diff is 60mm wider than the ke diff and the wheels were definitely not going to fit so started rolling/pumping the guard which ended up being a mess as they needed to be re welded, bogged and painted. I've got them done now good enough to put the new diff in and see if it will fit but they are still going to need some work before they are perfect. Also cant decide whether I like the wheels better in black or white....
