Hey guys, Thanks for the input. I checked with Federal Mogul about the seals. I told them exactly what I was working on and they put me on hold and looked up the part number that would work. They said that I could install these without modifying the guides. I was going to use positive seals, but they told me that I couldn't use those without modifying the guides. I am going to see if I can isolate the cylinder that is causing the popping and then check it out further. I will post what I find out in the next couple days..

Be Happy and Live a Good life filled with Love and Happiness.
