The model no. we have does not include the last three letters LBD but I dont think it matters. We are preparing to have a reconditioned clutch kit ready for when our existing clutch fails , but we need confirmation on the specs of the existing or what should be in the machine. I believe it should be a 14 inch Lipe-Rolway pressure plate with a 3/4 inch step in the flywheel and 14inch wet plate with 1 1/2 inch 10 spline centre. The parts drawing depics what I consider to be a Borg and Beck pressure plate but may have been used as an available convenient drawing.
