Slip Yoke

I want to put a grease fitting on my slip yoke to aid in future lubrication so I don't have to do complete disassembly evertime any ideas on where to locate it?

I have a 98 Rodeo and we put the fitting between the splines on the front end of the drive shaft. Did this about 4,000 miles ago and is still working great, no clunking.
