So I have most of the parts to do a chain drive conversion on my xb9r, however every guide I read uses a tensioner from EBR which no longer exists. There are a few that use a 20 tooth sproket punched for a bearing. But I was wondering if anyone knows of a part number that would work for the tensioner. There was a gates part number off a disel engine but that was confirmed to be wrong part number. Any help would be greatly appreciated.
