Lancair sells these. I bought a pair a year or two ago. If memory serves there were $50-ish each.

George,

If the IV/IV-P was built according to the plans, the two fuselage jack points should be immediately forward of the main wing spar box and about 20” either side of the fore/aft centerline, on the bottom of the fuselage. The jacking “cups” thread into vertical steel tubes that are bolted to the front of the spar box. These should be visible under the front edge of the pilot/copilot seats. If you’re looking from under the airplane, they should appear as two round 3/8” holes, and a 3/8” fine thread bolt should screw into them. The jacking cups themselves consist of steel “cups” that will fit over the top of a jack head (about 1” in diameter) with a threaded 3/8” shaft welded to the back side…this part screws into the fuselage.

Hope this helps.

Where are these points located on the fuselage?
