Steering Gear Box

I have a '64 G10 Panel Van. I have been removing and cleaning the underside of my Van project. Steering box looked like a big grease ball. After cleaning it up and refilling with fluid, it appears to be leaking around the output shaft (pitman arm). Books shows a seal at that end. Anyone have a source for that seal? Local parts stores don't seem to have a clue.

Thanks.

I would put grease in it,,,,,,the seal probably is GM 5670325,,,,,,,Napa NOS 11055

Thanks, donivan65. I will run those numbers past the local boys and see what we can come up with.

I had the same issue with mine also..!!! Car Quest Auto Parts had it (Donivan's Part Number)  and it is a job to get it out take your time not to damage the shaft I used a angled pick...  

I would try running grease in there to see if it stays in before messing with that seal,,,,,,,there might be a worn out bushing there causing the problem......
