im using a right helical clamp on my blazers, your right the length doesnt give much t work with but you can get a little. i remember reading some where that when using the old fashioned fletch tite that comes in the the metal tube you should use alcohol to clean the shaft, but if use the super glue type fast glues use should use warm water. i began using the water instead and saw an improvement in my adhesion.
