All the Max Wedge cars came with 7260 joints, I ran them in my low ten second Duster until the 8 3/4 housing twisted itself to death Make sure and get the HD solid cross shaft joints no matter what size you choose, not the greasable ones I did break a greasable 7290 front U joint and trans yoke in that car, not sure which broke first It now has a 7290 HD solid cross shaft front yoke and U joint and a 1330 or 1310(not sure which number it uses) rear U joint to match the stock Dana 60 pinon yoke
