67 Clutch/Pedal Covers

[Gerard F.]

Just going through my boxes of replaced parts from my 67, found these and thought I'd document them:




The part number below is what could be read on the back of them.

Now you know why I replaced them with repro's. But the repro's still lose points, as they don't have the raised moulding strips along the back.

Maybe I'll try these next time out, and see what I get off on condition.

They seem to have some yellow glue on both on the bottom, like something dripped over the face. But that could be something I stepped in over the 35 years they were on the car.

Jerry,

Which vendor sold you the repros that got a deduct?

Looks like a generic GM pedal pad that had a lot of cavities - mold #48 and #53

Re: 67 Clutch/Pedal Covers

The reproduction pads (also sold in later years as GM Service parts) are molded from rubber with a significantly lower durometer (softer) than the originals, and they don't grip the pedals very well; I glue them on with weatherstrip adhesive.

In the plant, we had an air-operated bench-mounted 4-finger spreader tool that pulled the four flaps back to install them on the pedals; you couldn't do it with your fingers.

Within the past one or two years I thought Wilcox came out with a repro pedal pad that had fixed the soft durometer problem. That's why I who Jerry bought his repro pads from that got a different kind of deduct.

Gary,

Not sure who the vendor was as it was 5-6 years ago. But the bags I saved for the originals had a vendor part number of LS415.

John,

I too replaced my clutch pad with a repo, which doesn't stay on. Could you provide more info on the weatherstrip adhesive?

Thanks!

Re: 67 Clutch/Pedal Covers

The numbers translate to Lone Star Caliper 415. Those come from Keen Parts Inc. in Ohio. The molds have TMCS inside as those are the oldest of the repos done by Terry Michaelis of Ohio.

I believe Corvette Central is the other supplier which have a harder rubber. (higher durometer)

They are both not perfect but what is perfect in the Corvette World. Any hack judge with a clipboard in his hand can find something wrong with anything.

I bought a pair from GM not to long ago that was soft. they were not in sealed bags.

Re: 67 Clutch/Pedal Covers

The brake (standard) & clutch pedal covers I took off my '67 were embossed on the back inside AY 6256368 (in 5/32" characters) along with a 38 on one & a 56 on the other.

I have seen other covers with 6256368 AU (in 3/32" characters) along with mold numbers.

As Joe pointed out, covers with TMCS in the back are reproductions and as other have noted are a "softer" rubber composition and can be detected by the "squeeze test."

Pete,

Another problem I was told by a senior judge, was that the reproductions lack the little molding ridge along the back of the pad. You can see that ridge in the photos above. I know this is picky, but if the ridge is not there, it is a minor configuration issue.

Are we really supposed to do the "squeeze test."

And here I thought I still had air in my brake lines .

Joe -

I've used good old 3M weatherstrip adhesive; contact cement would probably work just as well.

John did all the plants use this method, you told me you worked at the Willow Springs corvair plant not at St Louis Corvette plant. Phil 8063

Yes, all Chevrolet plants used the same fixture to install the pedal pads. I worked at Willow Run, Flint Assembly, Flint Pilot Line, Chevrolet Engineering, Norwood, Lordstown, and St. Louis-Corvette, with shorter launch stints at Van Nuys, Tarrytown, Janesville, and St. Louis-Passenger.
