I managed to get a little time last night to build up the new rear diff that I'm going to try in the Procat at WBMCC at the end of the month. I will be removing the MMS rear box and using that on the XLS that I will soon be building, and going back to the custom motor plates I had made.
I managed to build this bosscat pro diff out of completely new parts down to the nip Schumacher diff balls and thrust race.
And now in it's new home
Just need to strip the rear of th Procat now for the belts and re assemble when I get some spare time.
