I posted this elsewhere too and was told all aftermarket leafs are 2.5, from 73-87 regardless of 1/2, 3/4 or 1 ton application. Apparently the stock 1 ton leafs are only wider at the ends (3"), but they narrow down to 2.5 at the spring pad. Aftermarket springs make up the difference with wider bushings for 1 tons. So it looks like I was worried about nothing, and can use my lift springs. Good news!
