For the front grease nipple on the propshaft UJ you need a Sealey 170mm Needle Nose Grease Gun (very cheap on Ebay). Clean off the nipple, fit the needle gun to your regular Wanner-type grease gun and hold it hard into the nipple hole while pumping. This makes doing the front U/J the work of minutes (assuming you have a lift) and does not require any cutting of floorboard or trans tunnels.
