Are the spider gears in a gov-lock the same as the ones in a GM open diff. I tore down my rear and found the one spider missing teath. The diff works fine except the missing teath. I need to get my truck back on the road quickly (just warmed up enough to get tare into it but suposed to get 12" of snow this weekend). If the spiders are the same I am thinking I can put get the spider gears and put them in till I can up grade the rear.
