Just rivnuts through fibreglass doesn't sound secure enough to me, although it sometimes seemed like Harold was happy to use self tappers into fibreglass wherever he liked!


Yes nuts and bolts on the forward edge of the tank and large self tappers on the rear edge of the tank.

I must admit when I first built my MK2 I was a bit skeptical about using self tappers wondering whether they would take the weight, but I must admit they were fine. On my rebuild I just used stainless ones instead and still no problems, touch wood ;)

When I stripped mine it was self tappers along the rear of the tank, seemed solid enough. I did think of going down the rivnut route but the f/g is too thick

Re: Mk 1 Project Zippy. Getting Horny.

Trouble is, my holes had worn to the point where I would need a screw about 1/4" thick. I thought that rivnuts would be a better idea. I am not expecting the epoxy resin to give way anytime soon.

Let's talk about horns. Initially I wanted to use a set of air horns on Zippy, but from what I remember you cannot use just an air horn on a car of his age, so I would either have to use a standard horn or a combination of both that and an air horn. This lead me to another problem (normal with this car) - space. There is not a lot. Having decided that a decent loud "normal" horn would be the best way forward, my brother bought me a pair of high/low tone horns from CBS. I have tested them. All I need to say is that "Holy **** they're rather noisy". I will not be needing air horns.

Now, where to put them?? My initial thought was somewhere close to the radiator, but with the fan and the oil cooler in place, space is at a premium. So I concentrated on higher up in the engine bay. The offside inner wing fairly close to the bulkhead provided an adequate empty area, so a bit of measuring saw a CAD template made. This was turned into steel, drilled and bent to shape, before being painted. A couple of rivnuts and all was ready to go on. I'm happy. Wiring will follow.

A suitably empty space for the loud pair.
