You are correct - the LAT brochure does show "two specially designed 'hold down' clamps". I do not recall ever seeing them on an LAT hood. The resolution of the scan of the brochure I refer to is not high enough for me to tell if they are pin type or if they use some other connection method. At first I thought the location was where the hood bumpers are located, so the threaded fitting could be used for the "pin" (or whatever it is that is attached to the body). But that would put the hole for the hood part of the clamp too close to the corner and could cause cracking. So the clamp is located further towards the center and further away from the windshield, to where a hole in the fiberglass should not result in a crack running to the edge. But that begs the question - how was the part which is attached to the body actually connected to the body? Did the dealer installing the hood have to drill and tap somewhere into the body? Maybe many of the dealers did not bother installing the clamps. But if the bonnet clamps came attached to the hood or if there were holes in the hood for the clamps, then the dealers would have had to install all of the hardware.
