I have read that 3tc water pumps can be fitted to 2tc engines, and that these pumps have a shorter impeller shaft. I have recently purchased an aluminum radiator from BRD Racing for my TE27, but I am having clearance issues from the extremely long impeller shaft on the water pump. I would like to just switch the pumps, but I do not have a later style pulley nor do I know where to find one. At nearly $100 for a new one from BRD, I would really like to save some cash and buy an old original pulley. Does anyone know where I can find one?
