I may have to go that route, but was hoping to find where someone had modified the existing crossmember. If not, I will and post my pics. I've got the game plan but haven't got to the point of trying it. (By the way, not that I have a need for it, but I have a roadranger ten speed out of a 78 gmc Brigadier. Does this tranny have the overdrive also?(I was under the impression that only the 13 speeds had the OD.))
