right, narrowed it down the the bj4 worlds slipper,
can someone tell me what the distance is from the outer edge of the bearing to the other bearings outter edge?
edit: i emailed jconcepts about which bits make up the slipper(they wouldnt give me dimension

) it says i need
1120 - Outdrive male
1121 - Outdrive female
on the bj4 review the outdrive looked the same, or is the female and male for the internals as in the nut or bolt?
