Looks as if you are in Minnesota and I don't know if you have a Grainger's Supply there. Google Graingers to find out. They sell a 90 degree tip that I use with a total height of 5/8" from top of the zirk when installed. It slips over the top and you push it down. Trying to describe it.. The zirk pops into it's side. They do not last a real long time since there is no way to tighten it up after the spring keeper wires loose their tensil but it works for a good while. Another idea is to remove the ball top zirk from the grase port and replace with a button type. If you do it this way, you can make a small piece of hose with a female button fitting that would attach to the male (installed) buton head on one end and a male ball type on the other end of the hose. You can just slide it off when you are done greasing that point and continue to hit the other zirks as usual. (No grease gun head changes). I typed for a while truing to describe both of these. If I did a poor job, please PM me and I'll try to do a better job. Maybe even a diagram if I can figure out how to attach it. Graingers sells all of what I tried to describe.
