I need help trying to find out the difference in the front hose shrouds Clark's shows ether CU159,62-4 or CU160, 65-9 for the left. For the right side CU195E, 61-3 except turbo. CU195L 64-9 except turbo. CU3062E, 62-3 turbo. CU3062L, turbo. These are going on a 66 140HP. I have some off various engines. Thanks in advance, Bob
