I added one leaf to each side about 1976 due to severe wheel hop on acceleration. This raised the rear body about 1.5 inches. Still good today with zero sag after 40 years.
this seems to be the best direction. 1 1/2 would be plenty. wheel hop is not my issue. i just can't get a grip. i'm running MT 29x15x15 so that shouldn't be an issue. i'm sure it's because of the air shocks
