66 fuse color and black phosphate question

[Tony C.]

Can some one please help me with some question about colors.
Are the fuses in a 66 color coded. Long Island Corvette sold me a set that are color coded but the Judging Guild on page 35 has (these fuses are NOT color coded).
Need help with more color.
Are the two 1/4" thick nuts on the clutch push rod that holds the swivel in place black phosphate or zink.
Is the nut that holds the clutch ball in the Z bar to the bracket black phosphate or zink.
Are the nuts that hold on the master cylinder to the brake booster black or zink with a black lock washers.
Dose the brake booster hose that goes to the intake have a swan logo and FC -1 on it with black clamps as per Long Island.
I looked in the Judging Guild and I could not find the answers.
I know it's a lot but I can use some help.
Thanks Tony

The nuts for the master cylinder-to-booster and the clutch cross shaft-to-frame bracket were exactly the same. They were black phosphate-finished.

The nuts for the pedal push rod were JAM NUTS and were zinc finished.

Re: 66 fuse color and black phosphate question

According to the story I printed in The Restorer -- and I heartily recommend you look it up for yourself -- the colored fuses started in 1967. Now if your car is a late 1966, I would especially recommend you look for that story because I can't recall if the author specified SOP (Start of Production) 1967, or some other more precise introductory point.

Tony,

Joe Lucia is absolutely correct, as usual, on the description of the 124829 thin jamb nuts that the AIM calls for on the clutch rod adjustment.
However, something very unusual occured on the assembly line starting in early part of the 65 model year.
Even though all 63-67 AIM's called for the 124829 thin nut, some time in the early part of the 65 model year, the upper nut was replaced with a nut of standard thickness. So, one thick and one thin nut for at least most of 65.
For 66 and 67, both thin nuts were replaced with nuts of standard thickness.
Typically, any time a change in part number or procedure occured on the assembly line, it's also shown in the AIM but this is one of those rare "non authorized" changes that never made it to any documents.
The nuts were either plain or dull zincad plated but I don't remember which.
