Howdy again, sorry I spend most of my time over on the 67-72 site so I don't log in here very often. If you haven't found your rear axle seals yet, it appears NAPA Auto may carry what you're looking for. They show 3 different styles, depending on which rear axle you have:

Yours is probably #1 or #3 since I believe only the GMC's came with Dana 44 rear ends in the 1/2 ton models. Good luck. If you ever need a quicker response you're welcome to contact me via email: markeb01@comcast.net. Regards, Mark.
