Hi all, Im looking for some help regarding the steering lock lug on the frame stem. Im currently restoring an LI 150 special and need some help with dimensions, shape, location of it . This is the last bit of welding I need to get done before going for powder coat so any help would be greatly appreciated. Photos. measurements would be a great help

On a chrome ring Series 3 frame it's 60mm from the face of the lower bearing race (where bearing sits) to the top of edge of the lug. I believe the combined thickness of the chrome ring and lower bearing race is 10mm, making the distance from top of frame to top of lug 50mm. To the best of my knowledge the width of the curved lug is the same as the one welded onto the forks: 35mm, but would be happily corrected.
Please post any findings / precise measurements here for future reference.
