Landing Gear were Landing Gear. They weren't specific to any SE frame. from 78-82 SE only offered all of their stuff piece by piece. If you wanted a PK Ripper frame, it had it's price. If you wanted a Quad frame, it had it's price. If you wanted Landing Gear, you bought them separate. A PK Ripper didn't come with LG forks. They were purchased separately. The no hole dropout Landing Gear were the very first run of Landing Gear in 1980. Rare forks for sure but not necessarily specific to PK Rippers. S.Brothers has an original finish looptail Quad that has matching no hole LG forks on it since new.
