Burns Bison Bass Tuners

Hi, Newbie here with my first post. IM in the middle of a bison bass project. It has been modded over the years and im trying to restore it to its original glory. THe two parts im having toruble with is the original bridge cover (been told i have a chance somewhere between zero and none!) and the oringal tuners. The long 'pole' style shaft with the black tuning key button. Anybody know if there are any knocking around? Even ones that LOOK the same will do but so far ive found nothing
