Wow, I called RPD one day with a dilemma over pin height for a super long rod on a long stroke crank. Jeff not only helped me by calculating the pin height I would need, he was doing on his luch hour and stopped eating long enough to help me out. I would still buy from him. Sorry you had trouble. Thanks to Jeff my 496 is thumping the ground. Now I just need to decide whether or not to junk the Pro Comp heads...... :roll:
