Ok. Makes sense. That's what I assumed initially, but my 40 had lap belts only. I figured the 3 point harness was a later addition and would have been roll cage mounted.
Still 50/50 on if I want to keep them.
In the planning process of cutting down my 40 to 45 ish length. What are these three threaded holes in the hardtop used for? Any benefit to keeping them. I can cut the top two ways, the latter would keep the holes. They would land above/below the pop out window after the chop.
