I am trying to complete my ring compressor sleeve collection for builds that I am finishing up. I have a 1968 428CJ that is fresh bored and honed to 4.160", and I hate using the expandable ring compressor sleeve. I have tried to find one from Summit, but they only have 4.165" listed for any supplier. I really like the Wiseco compressor sleeves that I have for other engines, but they do not offer them in 4.160" What do you folks use? Part number? Joe-JDC
