For me, the Jeep shaft is economical. $130 and done as long as the current clutch package is in good shape.
My second preference would be the 14 spline clutch disc. It’s under $100 IIRC but involves work to swap it out. Then use a die grinder to trim the clutch disc hub splines so it can move back off the flywheel properly.
Both will require a trim of the shaft pilot tip.
