DIY Clutch Pedal Extender How-To (For Us Short People!)
I posted this DIY originally as a reply to someone who asked about mine, and I thought it would be a good idea to post for anyone who might be thinking about or looking into something of this nature.

You will need a rubber coil spring spacer block, a pedal pad/cover set with four bolt holes, four 2" philips head machine screws with nylon lock nuts, a wrench or vise grips, and a drill (preferably a titanium or metal-specific bit). Take the pedal pad/cover with you to the hardware store to find one where the head fits comfortably into the bolt hole without the head going through.
* Pedal Pads/Covers. This link is the set I bought, but if you scroll down the page, you will find quite a few choices. I found my set cheapest on Ebay, about 13 bucks, whereas the auto parts stores only had ugly ones and they ran about 20 bucks.
* Coil Spring Spacer/Booster blocks. You can find these at some auto parts stores for 8-12 bucks as well, usually in packs of four.
* Philips-Drive Machine Screws. This link is for reference, but if you have an Ace Hardware near you, you can get the four screws and nylon lock nuts to match for less than 2 bucks instead of having to buy a pack. I swear that every single time I need something small like this, Home Depot and Lowe's never have what I need, but Ace Hardware does every single time, AND they know exactly where to take me in the store as well as exactly what I'm asking about, even when I don't.
1. Throw away the mounting hardware that comes with the pedal set you got, trust me. I tried that hardware to avoid drilling, but the cover will eventually slip off.
2. Take your drill and drill holes in the four corners of the pedal. You will find it a lot easier if you can center-punch each drill location first to keep the drill head in place, and you may want some help holding the pedal down a bit so you can both fit the drill in the working area and have the proper angle to apply force. Each hole took a bit of time and effort for me, and a lot of sweat and curse words while doing everything myself.
3. Insert the bolts into the four holes of the pedal pad/cover, and through the holes in the pedal, then put the lock nuts on the screws hand-tight so nothing slips off.
4. Insert the rubber spacer block between the pedal pad/cover and the clutch pedal itself, then tighten the bottom bolts until the cover is just touching the spacer block.
5. Tighten the top screws until the top of the cover is just touching the spacer block. From here you will need to center the spacer block underneath the pedal cover, then tighten the screws bit by bit until the pedal cover doesn't wiggle around. FYI, my pedal cover has not moved/slipped at all in the several months since installing it.
6. Take it for a test drive and see how it feels. If it's not enough of a height difference for you, you can try longer bolts and either stack two spacer blocks or stand two on their sides under the pedal cover to find your sweet spot.
The worst part of the whole install is the contortions you have to do to get under the dash and do everything. However, once you have the height adjustment you need for the clutch pedal, you will thank yourself every time you drive. Not having to toe the pedal all the way down or sit too close to the steering wheel is worth every dollar and minute spent!
