My Procat rear diff is too narrow.

Either my Procat rear diff is the wrong type, of the eccentric housings are the wrong type, because the diff is too narrow to reach the eccentric housings. The eccentric housings barely reach the outer edges of the ball bearings, so the diff wil fall out of the eccentric housings on either side when it's assembled. Now, my eccentric housings are white, while the plastic on the rest of the car is black, so I wonder if I somehow got hold of the wrong housings back in the day. I had shimmed the diff with washers to make it sort of work, but this means the four prongs on each diff output are barely engaged.

Can someone measure their eccentric housings to let me veryfi mine? Mine are 6,5 mm thick in total.

My diff obviously isn't the same as the one in the manual, as I have the hex washers, so I'm not 100% sure it's complete. The picture shows the parts my diff is made up of. In addition to the puleys with balls, I have hex washers, hex carriers, bearing and shafts. Does it look right?


I have made myself some CNC-milled aluminium ecentric housings that I will try to use, but I'd love to have the Procat as original as possible.
