Update on this, managed to adjust today and all four go in and now gives a really tight fit. Really impressed with the quality of this product and could easily pass as an officially made CF targa top. Definitely the best of both worlds.I'm also struggling. I can get 2 latches in easily, one is a really tight fit and requires some force and the fourth one I can't get in fully even after following the instructions and making various adjustments. Fully agree on the quality of the product.
