I have a fiberglass bonnet, so the option of welding bits to it were out! I did consider Dzuz(?sp) fasteners and hood pins, but I like the "Spit" latches and they offer a nice, positive hold-down! I am not crazy about the screws on each side of the latch but I can live with them, and if I had a metal bonnet I would have considered welding the mounting brackets to it. Remember, a word of warning, if you are attaching some kind of hold-down through the top of the bonnet, rather than the sides, the sides do have a tendency to "splay out" sometimes! I will post a couple more pix of my install!
Here is a picture of the hardware used, the latches were purchased off ebay and the U-bolts came from Home Depot!
