Thanks Bill. I just called Nappa across the border in Niagara Falls and they say they have the seals. I could not find them here in Canada,and was sure I checked with Napa last July with no luck. Tomorrow I will call my tranny tech friend and make sure what I need. I just assumed this would be a Dana 20 transfer case....that's what I asked for from Napa and they agreed that the seals are spring loaded ( if that's the right term ), two are the same and the out put front seal is different. Maybe my search is over. What other transfer case did GM put in the 63 suburban 4x4?

Thanks again Bill.
