I HAD a NOS front one for a long time, we got it by mistake at 63436, and just sort of "put it in storage".

We didn't even know what the H it was for when we got it ...

Years later, after 63436 was done, and I moved to Florida, I kept it around for a while, and I THINK I gave it to Ted Stephens at a Garlits show one year. At least my buddy says I did.

I didn't see much chance of finding more, and didn't much care for them anyway.

Only other one I have ever seen was a left rear on a coupe, in a jy near Tampa, had been worn thru by the tire, So I left it where I found it.
