New 1976 Blazer owner need help please
 

I just bought a 1976 blazer. The transfer case is leaking from the front and rear output seals. Can someone help me find the part numbers to these seals? Id like to get them from oreillys and put them in myself. its an all time 4wd transfer I believe 203. Thanks

A part number that i found is from Autozone 8 1/2 ring gear the front is DRK339B and the rear has two options 8 1/2 ring gear part# DRK321 and 8 7/8" ring gear part# DRK322
Dont know if that helps but good luck

Also make sure on that rear output that its leaking out of the seal and not the center of the yolk. Either way when you replace the seal fill that area with silicone
