I am in desperate need of the variable speed sheave for a 70's John deere 170. I am needing inside sheave, closest to the gearbox. I know these were used in mustangs and case skid steers as well. D57831 is the original part number. I have searched the internet and salvage yards for hours with no luck. If anyone could point me in another direction I would be grateful.I would imagine this gearbox was used in other applications as well.View attachment 3858
