I have a 1989 D4H that I need to replace some pins and bushings in the blade c frame at the tractor frame and the pin at the blade tower. I have called the cat dealer but they can not figure out which blade I have. The ser# is 8PB03466. I also have a parts list as well but can not figure out which blade it is exactly as well. it looks like it could be 6Y1970 or 6Y4897. just wondering if anyone here has any knowledge on what it could be.
