The only real proper kit was found by my local AutoNationNissanSouthBay dealer and the tenacity of service advisor Bob Spencer. Believe it or not the correct kit is for a 1974 Volvo 144 and is part number J5010-15927. Fits perfectly since the Volvo used the exact same British Borg Warner transmission. List price $63.59, net to dealer $26.78. Hope this saves a few more of the RL411 gems. And early 510 sedans!
