you can use timing tape and modify the stock pointer so it's all on the other side. works great if that's the only problem
you can also have a radiator shop move the inlet to the other side. have also seen people use two hoses and a coupler to get it to wrap around to the other side. neither is the best fix, sometime you do what ya gotta do. the best fix is use the timing cover, water pump and radiator from the same group.
