Nice 66 no-dash you have there. The proper original grips for it would be Target style with the 'football' (oval) cutout for speed loader use. However, any K/L sized grip for a square butt will fit the gun. Original Targets in good shape are getting expensive, so you may want to try a variety of styles. The smaller service style 'magna' grips fit my hand better on K and N frames.
