My first purchase with NPR. I had questions on part numbers and availability as well as needs for physical verification of the actual size of the pistons and was pleasantly surprised with fast and accurate replies. Once verified I placed my order and received a well packaged set of beautiful forgings. I cant wait to get them installed. Many kind thanks to all who helped along the way! I will be back to shop again. Merry Christmas to everyone at NPR. God bless you and yours. -J
