I have a practically new set up for your nailhead. It's got maybe 20 hours tops on it and made a huge difference in overall performance. I also have the original distributor if you are interested. It's listed on EBAY http://www.ebay.com/itm/330926488501...84.m1555.l2649 If anyone needs it here I will sell it for the start price of $200 plus shipping. I'm sure you know I spent more than $400 so this should make someone happy!! Email me at tony4one@gmail.com and we can talk. Thank you...Tony
