What you have there is a Glacier DX bush, which is polymer not PTFE lined.
If you wanted the PTFE lined type you wanted a DU bush. The DU lining isn't dimpled for lubricant retention & is a bronzey-beige colour.
DX bushes must be lubricated (oil or grease) – DU bushes can be used dry or lubricated.
As Chris said, just drill the hole where you need it & debur – which may be easier said than done, depending on the bush diameter.
