Default Just realized that there is allot of open space behind the pedals

From a previous thread I had posted, it was recommended that I put a stop behind the gas pedal to prevent putting strain on the throttle cable when reaching WOT.

When looking at building out a stop, I realized that the amount of open space between the gas pedal (actually all the pedals (brake and clutch)) is like ~6 inches or more.
Is this normal?
It seems that the pedal when depressed should be allot closer to the firewall.

That's the way it's designed.
NOTE: Two stops could/should be installed or manufactured.

One CLUTCH PEDAL STOP.

TWO:GAS PEDAL STOP.

Wow, you'd think with a little enginering it would be possible gain another 6 inches of foot room space by getting the pedals moved back.

Well I've discovered that re-engineering things is not my forte, so I will stack two 2x4's against the firewall (plus minor adjustments) and call it a day.

Actually, the clutch pedal will come within a 1/2 of the firewall or hit the firewall depending on what system is used. Hydraulic, (which it was never designed for) definitely needs stop.

The brake pedal should have a major amount of extra room in case of brake component failure. The CR's gas pedal (OEM) should already have a stop built in.

Oh yes, dozens and dozens of engineering improvements could (and should) have been done years ago, but remember CR's Cobras were designed to use '70'sdonor parts.

New "ways", different parts over the last 40 years requires some hard "home" engineering every time a new "assembly" is used.

The CR's gas pedal assembly that I have does not have a stop... I have a CR1 kit (and the assembly looks just like the one on the Assembly Manual. The stop must have been added by Bill with CR2.

I would be interested in how Bill/CR2 modified the pedal assembly to incorporate a stop for the gas pedal.

I already put one in to prevent the throttle cable getting slack when not engaged.
The otherway for pushing on the gas pedal, I am guessing that building out the floor to stop the pedal (with something like a 2x4 is probably the best/easiest to go) as this should eliminate stress on the arm when reaching bottom.

You've lost me.....BILL?
Not the cleanest not certainly Hi Tech, but works great and allows adjustments overtime if needed; use a long 3/8's bolt through the firewall, put a "nut" inside and out on the bolt. use the head of bolt for the stop. Time to adjust? Loosen up both nuts, adjust the bolt where you need it

I meant Don Scott. Bill is his son.

I will look into doing the bolt method through the firewall.
I am still thinking that it would still put stress on the arm/pivot linkage but it would be cleaner.

No stress involved. If your thinking on the stop bolt pushing hard or continuous on the firewall then just cut a 2x3 10 ga. piece of steel, center a 3/8's
Hole in the plate, put this on the inside "under" the carpet, INSTALL AS BEFORE Slam the pedal at will. ��

I replaced my throttle cable this winter, before cutting the cable to size it is important to hold pedal to floor. Try adjusting your ferrel at the Carburator or linkage. If not enough adjustment, I would buy a new cable and cut to correct length (allowing for pedal to hit floor). My pedal has no stop but the cable and linkage is adjusted so pedal is at the floor on WOT. Hope this helped?

Doing so, I think that would put the gas pedal at least 6 inches behind the brake/ clutch pedals.
Wouldn't that be undesirable?
I am thinking that I would encounter issues maneuvering my foot to hit the brake pedal.

Ken, could you post a pic of what your pedals look like. If your gas pedal sits further back than your brake pedal, are there any issues when pulling your foot off the gas and then pushing the brake (how skinny is your foot)
Thanks

You are right the brake pedal sits about 6" higher than the gas pedal, and 3" higher than the clutch pedal. I don't have any trouble working the pedals with my size 11 feet. I don't think heel toe braking would work but I don't race it. I would prefer modifying my brake pedal to sit a little lower, rather than raising my gas pedal. I did have the pedal assembly out to replace bushings, a real pain to get at but doable if you remove the steering wheel and seat.
I did take a photo, but i do not have photo bucket. If you reply to my email, I can send you the pick. kmalysa@zoominternet.net

Ken, I sent you a email...

I am going to ponder moving the gas pedal back... I am now thinking that to could potentially save me from accidently hitting the gas pedal while pressing on the brake.

P.S.
Another great thing about ClubCobra.com is that they provide space here in the Gallery section for you to upload pictures to.
