I've got this Hydrogear tranny spread out across my garage floor and I am in need of a parking brake assembly {PN 5966 }. That chunk of metal I found in the bottom of the transmission case belongs to the now defective parking brake. So after trashing 3 drill bits ,.3 punches and emptying a bottle of Mapp gas it is now removed and ready for a new replacement. Of course I'll also be needing the brake shaft seal { PN6449 1/2" ID } since I baked the one that's in there getting the old stuff out. Anyone have any thoughts of where and if these parts can be had?
