4x4 group buy and a few others have them- made by AA. Its B D20 for the bronco. The jeep D20 is different. The difference with the WH it comes with the CV yoke if I remember correctly and you can get it assembled with the new tail housing (d300 like the AA kit) or unassembled for your stock d20 housing. This route you wont need to adapt the speedo. I went this route
