Topic: Clutch linkage and pivots. What finish?

[1967 eight barrel]

What finish should be the clutch pivot frame bracket, bell crank and clutch pushrod be? The NOS engine pivot I have is zinc.

Bare steel originally on the assemblyline. Same with the Z bar.

What would best replicate the finish? Gray, silver, cast metal?

I would clean it with Evaporust and coat it in T9 to preserve it.

+1  except cleaning it would involve taking the zinc plating off by a acid bath . If blasing i would tumble in a apropriate meda to bring the metal back to proper appearance and then " coat it in T9 to preserve it." I would not paint it because the paint will fail where bolts go through and at pivot points .

That was my concern, durability long term. It seems all Ford service replacements are zinc plated, as well as the reproductions. Most of the reproductions don't have a welded pivot pin on the frame side either. Thanks for the information.

The Ford service versions changed to zinc plated in 1970 also.The repro market typically wrongly assumes that the last service replacement is good enough .

1967 eight barrel  first I would make sure you have the CORRECT 67-68  vs 69-70 Z-bar brackets as in your first post you said you had a nos zinc frame side bracket & the only zinc plated ones I seen were service replacements from late 70s-80s era as ford sold the 69-70 type to replace the 67-68 type after 69.  I have never seen nos 67-68 brackets unless they were ordered back in 67-68. I pointed this out years ago to some 67 Shelby guys & they never noticed the difference & the MPC calls the change out but never changed the # to a c9zz instead still used the (frame side) c7zz-7507-a & changed it to a - b & (block side) c7zz-7a572-a & changed it to a -b also. The brackets are same design but the adjustment holes changed from 67-68 to 69-70 FE engines. The 67-68 had round hole on frame side & slotted adjustment on the block side vs 69-70 frame side slotted adjustment & block side round hole. So you need to pair them up to be correct & the 67-68 versions are harder to find.      Marty I agree with you on the evaporust cleaning as you can save original plating & metal finnishs   (depending on the condition they are in) by soaking part in older used weaker evaporust & don't let the part soak TOO long & when you remove part wash off with water then dry & oil.   When you first remove the part from soaking DONT rub the part with anything as you will remove the plating just water rinse part off & if part isn't clean enough resoak part longer. We use this method when cleaning parts for survivor cars but had some parts clean-up good enough that didn't need replated.

Well, I definitely have the service replacement, being the adjusting slots are oval, (left to right.) I noted the cheap over seas reproductions coming in are just pressed in and not welded. There is a LOT of pressure on those pivots, and I see the splined pressed in pivot stud wearing quickly on vehicles driven more often.

kieth are you doing a concours resto as I have some 67 brackets in my inventory ?

[1967 eight barrel]

Ed, for the most part, yes.
                                    -Keith

[specialed]

are both of your brackets 69-70 as we know the nos service frame one is?

[1967 eight barrel]

Ed,
I don't know the difference on the block side. As a matter of fact I wasn't aware there was any difference until Bob had mentioned it.  Pictures would be helpful.

I took a quick picture. Of course the chassis side is not adjustable like the 6970 version.
