Trunion Joint starting to make Noise

Since getting the dart moving again, I've been hearing some noise in the trunion joint at the front of the drive shaft. No vibration, but a little annoying.

Does anyone have a source for a A-body B&T rebuild kit?

Atlas Obsolete on e-bay seems to think they are gold-plated or something at $150+, Thats about 1/2 the cost to get the driveline changed over. Just trying to get it to keep moving until I have the 8 3/4 ready togo in, at which point, I'll have a driveline shortened/converted to a slip-shaft to U-joint flange.
