You can always turn down the one inch bumper from Atlas. Attach it to a weight bolt, throw it in the freezer, after a while, chuck up the bolt, and turn to the correct diameter.
Thanks for the link. I see they sell Lucasi, but I couldn't find
any bumpers, even using search.
Are you sure they sell bumpers?
