Guess I should determine if I have a truck or car eng then cause I do not know what to compare the width with, Hold on, let me check with my Jim Carter's book, looks like 41 to 52 has 3/4 inch pulley and 53 to 55 has 3/8 inch so I would bet that mine is 3/8 inch, it is only about 102 so I will check later,,,I keep forgetting that I have his book around..thanks....Fred
