I would like to see this cut down like 1/2 or 1/4 inch all the way round (not as high) mainly just for venting as i dont like the vented inspection lid look.

 

It turns out that a friend of mine had an original vent sitting in his garage. I had a chance to compare the original to the Classic Datsun vent, and I noticed that the mounting flange bonded to the Classic Datsun vent adds at least 1/8" to 3/16" to the height. I'll try to find some time to make actual measurements. Otherwise, they look identical from the outside. I took some pictures of the original and I'll post them when I have a chance.

I just got my hood scoop from Les, it looks great, is waaaay stronger than it looks in pics, and lined up on my stock 240z hood perfectly!. I set it down on my Dad's 280z and it looked good on that hood as well. Les says he has one in stock now and they finally have all the production hitches worked out and can make them faster now. The only thing slowing him down is sourcing good boxes. It came with a paper template that will make mounting it a cake walk.

 

Side note: I spoke with a guy that has an original hood scoop that he bonded to the hood and he had issues with the hood flexing and it would crack the bonding at the edges of the scoop. I may eventually bond mine on also, so I am not going to hog out my hood with one giant oval hole, but will be cutting several smaller holes so the hood can maintain more of its original structural integrity. I may look for a large hole punch so the edges will be flared and add so strength back into the sheet metal. Also, I plan on making sure there are a couple good holes at the front edge so water won't pool up in there.

Doing something like that should definitely help any flexing issues. Maybe a bead roll X under the scoop and cut the "triangles" of the x out?

OK, so i ran into a few problems. One small one was that the paper template that comes with the scoop does not account for the shape of the hood. It was easily handled by centering up the template, then trimming out the middle of the paper that would run over the bulge on the hood. The not-so-small problem is that the j clips are not installed into the fiberglass symmetrically they are a 1/4" off hear and another 1/4? off there. The template does match the Off-placed bolt holes, but one of the holes on the back edge, by the windshield is set too far forward placing it directly over the edge of the hoods frame. This means you ether need to cut up frame or get your own clip and set a new hole. The scoop itself is in good shape, but I would have preferred it just came with a few clips versus them being installed semi-randomly.

 

I plan on shooting an email to Les to let him know as well. Unfortunately, I trusted the template, and drilled holes prior to realizing it was right over the frame rail. Maybe it will save some of you guys the hassle I know have of dealing with some extra holes.

 

I just looked at my own pic and realized the holes are pretty obviously "off".... look at the two near the back edge...the one on the passenger side is the culprit!

If you look at my pictures, you'll see that for the rear mounts, I put the clips on the side flanges and not the rear. They still line up with the hood frame, but they're in a location where it was just a matter of drilling an oversized hole through the frame to get the mounting screw though. Mind you, I have a crapy aftermarket hood, and the frame is set about a 1/2 further forward on the hood skin than an oem hood. So, just double check before you drill anything.

The scoop that Les sent me already had the clips glassed in and are proving a real %**$# to remove carefully. He and I are good and the part itself is awesome, the clips were just poorly placed. I recommended to him that he not place the clips, but to just send them with the part, that way it can be our fault when the clips are in a bad place. ;) I am still very glad to have the part and definitely recommend it to all. Just posted to make sure no one else makes the same bonehead mistake I did. :confused:
