Welcome to stovebolt.com. I can't answer your question as not familiar with the differences between maple leafs and US chevys and GMC's. Thru the early fiftys it seems more common for chevys to have the 5 stud on steer and 10 stud on rear. Some GMC's and late fiftys chevys had the 6 stud wheel. Which is better? I expect you will get answers on both sides.
