I love the ease of using 70's, 80's C10 15x6 or 15x7 wheels with doggies on our B body Ponchos our 66 star chief had the 14x6 and i put 15x7 and a tall 235/75R15 all the way around.. funny thing is the original th400 trans code i saw the factory speedometer / trans code chart showed our trans calibrated to the 2.56 gear and std 14x6 wheel tire combo , but the same speedo setup was also used on 2.93 geared car with tallest biggest 15 inch option up wheel tire and thats the gear I swapped in with the safe t track and those bigger tires by coincident.. of topic but carry on
