Default Which part is this - backdraft 3.5

I can't find the part # for this part in the schematic, here are pics:

(in the yellow the drive cup / axle looking part) - its the part that goes on the side of the differential, not the one for the front/rear.





This was the original part (broken):

you'll have to order the whole diff in order to get that part I'm almost sure . because I have the Earthquake 3.5 which has the same set up .

actually it looks like I found it - bs903-110 for some reason it doesn't show the part # in the backdraft 3.5 schematic but, it does show it in the backdraft 8E schematic. We already tried bs903-109 and that was just barely too long. The bs903-110 we matched it with the broken piece and they are the exact same length so it has to be it.

get some O rings from a hardware store. for that part to break, the driveshafts have to much back/forth play which wore out the drive cup. an O ring or 2 will limit the play, reducing wear on both the drive cup and driveshaft.
