67 Clutch Linkage Resto

[Dereck S.]

Looking to restore the components of the clutch actuation linkage on a 67. I could use guidance on the proper finishes for the pushrod, swivel, and jam nuts. The TIM doesn't have much detail. Attached is an image I took from an NCRS Bloomington car that has the above parts painted in semi-gloss paint. I'm surprised that the jam nuts would not be zinc plated. Please confirm what is correct for the finish on these parts?

Dereck -

Most originals I've seen look like the photo below - the pushrod is phosphated, and the swivel and nuts are either phosphated or natural. Definitely no paint.

Thanks John, I won't paint the parts.

John -- was the thick/thin jam nut controversy just a '65 issue ?

I'm not sure how that played out, but it's pretty apparent that the plant preferred both thick nuts, regardless of what the A.I.M. called for, because that's the way they built them.

They all weren't built that way. My 65 has a thin nut in front and a thick one behind the swivel. It's been that way since new.

Jim -- here's a pic of the general area on '65 VIN 23563, which has been off the road since 1973 (at least this was so a couple of years ago, the last time I passed by).

You can see the thin nut forward and the thick nut back towards the firewall.

My convertible was the next one off the line, and (today) has thick on both sides; my early '65 coupe has THIN on both sides. Of course, much can happen in 45 years, but there's been no NCRS owners prior to the 22/30 years (respectively) that I've owned them.

Wayne, That's how mine looks. I'm the 2nd owner and the car has never had anything done to it.

I agree with Wayne. The 65 model year was the year of change for the clutch rod nuts. All 63-64 had thin nuts. Early 65 continued using two thin nuts, as in 63-64, but at some point in production, this changed to one thick and one thin. Also very possible that late 65's used both thick nuts.

I'm pretty sure 66, and all later, used two thick nuts.
