I don't know if I've earned my wings yet or not... working on my Maco like a madman, though!

I've got to figure something out for my hinges as well... the "factory" hinges are barely acceptable... They allow the hood to move all over the place; way too weak for the mass of the tilt front end. I can only imagine what might happen at 120+ with a bunch of high-pressure air buildup under the hood.

Well done. ~Tim

One of the advantages of the fender louvers on the trans-am and Greenwood cars is to equalize the under and over hood pressures. I would love to find a set for my car.

I was just reading back through this hinge thread and read the above... the '96 and later Dodge Viper GTS models had upper fender air extractors in similar fashion that would look right at home on Corvette fenders; might be something to look into.

I have been reluctant to post this because I believe it will be greeted with a lot of skepticism. because as it was to me it just sounds too easy a fix and one of those "Why didn't I think of this"

I admit the first time I was doing a Mako I knew the Ecklers tilt front clip style pivot would not work as it was too low so I followed what the others here were doing,
Much thought , time and work has gone into reworking stock truck or car double moment hinges to work on the Makos,
What no one considered was that double moment hinges was only needed because of where the pivot point is within the front clip, move the pivot forward and up and a person no longer needs an elaborate hinge but gains a simple more sturdy single pivot point,
The Mako clip I just bought came with what I will call a well thought out pivot system,
While all I have at the moment is one crappy picture of the new clip, I did do a little test of my theory and while I have no scanner these pictures serve to show that where the pivot point is makes all the difference,
Please note the pivot points are approximate not down to the scale inch

This first picture shows a single pivot point about where everyone mounts the truck hinges on a Mako clip, or about like an Ecklers tilt front end would pivot.

Now with the front clip open we see how much overhang the beak has and anyone that has a mako knows this single pivot will not work on a Mako the beak drags the ground before the open is open wide enough to even check the oil,

So dual movement hinges were needed to open the clip up and forward,
But not the end of the story, there are more than one way to tackle a problem,
It's all about pivot location,
If we break out of the box and mount the pivot higher and more forward in the clip we get the clip to open as much as the dual motion hinge but from a single pivot,

Here is the picture of the single pivot on a car working very well and as you can see the clip is open as wide or wider than the double movement hinge set up. the ends of the pivot rod are bearings so there is no slop,


The builder did do one thing I don't care for and that is placing the pivot support in front of the radiator but that will be no big deal to move that out to the sides of the radiator,

I was under the impression the guide on yours were car/truck hood hinges, it's the same basic idea, and if the builder desires that mounting point a hinge like yours is a must have,

When I got here way back all I did was beg David for pictures of his hinges, when Motion sent me that clip that went on the 81 it was all bare on the underside, the buyer had to work it out, Rosen loved to answer questions with "I don't rememeber", when you have others doing your work it's easy to forget how it's built,

I can lay out my clip and take more pictures but it really doesn't matter until I have it on a car,

It's hard on small forums where you only have a few people posting then how many are building the car or are past owners,
You might have seen I hang on the other vette forum a lot, I am the black sheep there but I like having so many views and opinions on a subject,
