I picked up a new customer who needs a radiator for a Clark GPS15 serial # GP127-0069-9130. According to my research the part # for the rediator is 2793250. I found a used one but the customer wants only new. I ordered a new one from SMH but someone bought it just before me. I ordered one from Clark and again it was sold before I could get it and they have none left. Any ideas where I can get one???
