I have begun to get my '69 W500 w/ crew cab ready for a hopefully fun summer of camping with the wife and kids. While doing routine service to the truck i found that i do not know where to put the gear oil into the front diff. There is no visible filler hole. There is a large bolt on the left side the the housing half way up but looks very large for a fill hole. Also i put gear oil in the outer ends of the axel and the right side ran right out the bottom. This means my inter seal is gone. The axel is a Rockwell FDS 750 and the inner seal is C/R A1205-N-742 or a National #473458. Does anyone know where i can locate one or more of this seal and what i should do if i can't. Thanks for any help. Jeff
