What leaf springs to buy

on my 69 i have the stock hieght 6 leaf espos. i put them on in '01. at the same time my brother bought the same set for his 68 barracuda. i cant tell you what stock hieght is as i wasnt around when these cars were new, but my car hasnt settled and neither has his. for reference, on my 69 dart, the top of the 15" rims is 1" below the wheel well opening and it has been that way since i installed them. i have been looking for new springs for the new 74 duster and have been shocked by the prices. going by my 69, if thats stock hieght i wouldnt want any lift at all.
