Well, spent most of the day playing with these pedals, and here's how it went:
You can see from this photo the way the Snake Oyl pedals look in the car. Notice that the gas pedal is a bit shorter than the stock, but not bad. I didn't drill any holes in any pedals for the Snake Oyl, I used their fastening technique. The only problem was that I couldn't get the alignment perfect due to the stock pedal arm getting in the way. Check it out:
Here are the pedals compared to each other. Note how I had to bend both the upper and lower accelerator pedal brackets for the Snake Oyl to get it to fit properly. Also note the size difference between the Sparco and Snake Oyl gas pedals, that will come into play in a second. Here's the photo:
Installing the sparco pedals were much more difficult than I thought they would be. I decided to drill out the stock pedals and use the Sparco hardware. Unfortunately, there is very little room on the stock clutch and brake pedal to drill 2 1/4" holes cleanly, at the Sparco hole locations. Centering the pedals for function and appearance, I couldn't drill all the way through both top holes, they hit the pedal arm. So, I decided to tap 1/4 20 threads on the top holes, and use threadlock in securing the top screws which were 1/4" x 1". For the bottom, the largest hole size I could drill clean through was 3/16", and I used nylon locknuts to secure the 3/16" x 1.5" screws (didn't come with the Sparco pedals).
The gas pedal also required drilling, but it was tough finding an acceptable location. The bottom hole on the sparco pedal is very close to the gas pedal pin. My only choice was to align the Sparco pedal with the bottom of the stock pedal, or raise the Sparco pedal up about 1.5" higher than the stock pedal to clear the pin. I drilled the center hole first, so I could try the pedal at both locations.
My conclusion was that 1.5" higher up the stock pedal from the bottom looked quite funny. I then tried aligning it with the bottom of the stock pedal, and I thought it looked better, and fit my shoes and driving position better, but it looked short. The screws the Sparco pedals came with for the gas pedal were also way too short. I had to use some 1/4" x 1.5" instead of the 1" long ones in the kit. You can still see the stock gas pedal behind the Sparco pedal at the top. Standing outside the car you really can't see the top of the pedal, nor when you are sitting in the car. You can only see it when you stand back a ways, or when you crouch down to look, like I did to take this photo:
Overall conclusion? Not completely happy with either. The Sparco pedals feel better than the Snake Oyl, are really secure, and look better if you don't consider how short the gas pedal cover is. These are functional, so I'll probaly try them out for a while. I also think that I might give another brand a shot (ZAF?) before summers out, knowing myself quite well. The shortie Sparco gas pedal will start to bother me eventually. If it were longer, I'd be happier. (Too tired to make a joke at that last line...
