there was another post floating arounf bout grips and putting them on basically as the guy above me saif hairspray tho dont use too much just enough the cover the area the grip sits on slide the grips on while wet and leave overnight maybe 24 hours and they should be stuck on ......otherwise if you have an air compressor you can slide the grips on a little and put the tool under the grips and trigger some air under them and just push them on.
hope it helps.
