2.66 first gear for O/D transmission

Can the standard O/D gearset be put in my iron case?

No, the input shaft bearing is larger in diameter on the O/D gearset and will not fit in a standard iron case.

To get the ratios you want 2.66:1 1st gear and have O/D you would have to use the Passon Performance 18 spline gear set. It fits a standard 23 spline case. The conversion kit cost about $2000 last time i looked
