I have a 53 Chevy ¾ ton that I’m working on the two piece driveshaft. I am having trouble finding the oil seal that goes in the end of the tube to keep oil from leaking out near the support bearing. If you are standing on the driver’s side and look at where the first shaft joins the transmission, then follow the tube back to the support bearing. Just before the support bearing inside the tube there’s an oil seal (National 1-34) is what mine had. I can't seem to find anyone that has this seal.

Has anyone replaced the bronze bushing at the tranny end of the tube? Can't seem to find that one also.

I beleive that I have a new bushing and maybe a seal.

Thanks, But I think I have it under control. I was able to find the seal from a local bearing supply company and I will need a custom bushing because of the wear on the mating part. I have order a standard bushing and will turn it to fit.

How much wear on the mating part?

I had 0.004" wear on the yoke, so I made a fixture and ground the OD surface on the lathe. I will bore the bronze bushing to fit with a RC5 running fit for oil.
