Default Gas Pedal Replacement

Guys broke my gas pedal. Saw a couple of old posts but no photo's or info on how to replace it. Also saw a listing for RD Racing and CorvettMike making more durable replacements but all links were broken and e-mails no good.

Any help appreciated.

These are hard to get to to replace the cable once you install the new pedal assembly but it can be done. If you are double jointed and have small hands it will be easier.

Here is one source: http://www.corvettepartscatalog.com/...roducts_id=615

I didn't see what year yours was, but the LT1 uses a different pedal than the one shown above. I would recommend using a factory pedal not an aftermarket. If the dimensions are off just a hair it won't swivel properly and the bushing diameter is critical. If you can't find a new factory one, I would get a used one.
As for installing it; with the seat all the way back, I was lying on my back and its partly by feel once you see whats going on with the cable. If you are 6'5" with big hands, you will need to get someone smaller to do it. Its a bit of a PITA but very doable.

I'm 6'4" and have done it lots of times

Gas pedal replacement is a snap on these cars. two 10 mm bolts that hold it to the firewall and a little plastic clip that holds the throttle cable to the pedal arm.

With a long-*** extension you can remove the two nuts while sitting in the seat. The clip, too, but it's by feel since you can't see it.

Grab the bottom of the pedal with one hand, the top with the other. Feel the clip at the top. Squeeze the back of it and push it forward (or rotate the pedal from the bottom, pushing the top toward the firewall).

Seriously, 10 minutes.

You can get a used pedal from one of the guys parting out a car for about $30 shipped. At least that's what I paid a few months ago...

I've used an LT1 pedal in a L98 car and vice versa. Just check that your TPS goes from 0% to 100% and you'll know it's working properly. Actually it's more like 5% to 95%, but you get the idea.

Just pull the seat.

Remove the seat cushion and four bolts. DONE!
