[rufus330ci]

Sorry for my very newb question but I have a gasket that is too brittle to put back in. I'm not sure what its even called or what size I need can anyone help me get a replacement.

Here is the picture -- I need the rubber gasket that sits in the Dust Cap that screws onto the slip yoke for the rear drive shaft of a 1979 K5 Blazer w/ a 350ci / Turbo 350 NP203 and 12 Bolt Rear I'm hoping its only a couple bucks. Thanks in advance!

I believe that seal is splined to match the shaft splines, try a driveshaft shop locally of call Tom Woods or Denny's or similar 4wd suppliers.... Look in the back of 4WOR or 4wheeler mags.

Agree with above. A quick google search came up with Dennys, but you have to know spine count and/or diameter.
