I decided to upgrade my shock bodies to the newer style that allow for the stepped upper shock guide to be used, in my case for the new delrin guides. The ones that I received have a lighter color anodizing than my original EB-48.1 shock bodies, but still have the smaller diameter shock shaft hole . I did some homework and found that there wasn't a running Part number change, I ended up drilling them out so they now fit the new guides, anyone else encounter this situation?
