The part number for the pinion seal is 411330N. The felt is 5M88. The sleeve is 99259. The wheel seals are #2081. These are the National brand. The pinion seal was used on most 3/4-1 tons up to 1972. The wheel seals were used clear up into the 90's. Did you check a local parts store? It seems there would be a lot of Chevy trucks in that area. Our parts stores have parts for europe & asian vehicles. The sleeve is expensive for what it is but cheap for what it does. Let us know if you can't & i'll see what it takes to send them. George
