Does anyone have pictures of original or suvivor 69 4-speed shifter linkage, the shifter mounting bracket, clutch push rod, and the reverse lockout rods?  I would like to confirm the correct plating, paint color, or natural steel color, of these various components listed below.  Or, can you confirm what is considered correct per judging standards.

The colors/planting I have listed below are what my originals appeared to be, but would like to confirm.  If you could copy and edit my list and include the correct color or finish after each item would be helpful.

Jerry MacNeish’s book, The Definitive 1969 Camaro Z/28-SS396 Fact Book, shows black and white photos of 69 Z28 linkage and levers.  The levers appear to be natural steel, and I believe the 1-2, 3-4, and reverse rods were dark phosphate plated. 

This is the list of items I am referring to, organized by section as called out in the 69 AIM:

UPC 7, Sec. C3, Page 112 covering Clutch Shaft & Push Rod:
Item 17 Rod #3849703
Item 14 Nut #124829
Item 18 Rod (threaded portion) #3840843
Item 1 Shaft Assy # 3899013 (bell crank) – natural steel, no grease fitting but with red push in cap?
Item 9 Bracket #3932760 – 40-60% black gloss paint, zink dark silver or natural steel?
Item 8 (3) screws #9420603 – dark phosphate?

UPC M20, Sec. A3, Page 324 covering 4 Speed Trans-Lever & Bracket Asm:
Item 2 (2) bolts #9420950 – dark phosphate or zink dark silver?
Item 3 screw #9789597 - dark phosphate or zink dark silver?
Item 4 support asm (shifter mounting bracket) #9791899 – natural steel?
Item 5 special nut #3955770 – dark phosphate, zink dark silver or natural steel?
Item 10 & 11, shifter attachment bolts #9419062 & 454950, and associate washer and lock washers – dark phosphate plated?

UPC M20, Sec A5, Page 326 covering the 4 Speed Trans-Levers & Control Rods:
Item 1 & 15, the Reverse #3955769 & the 1-2 & 3-4 Levers #9798541, natural steel?
Items 10, 11, 12 Washer, Lock Washer & Bolt #9418967 (TR head marking?) for levers – dark phosphate?
Items 2, 13 & 14, the Reverse, 1-2 & 3-4 shifter rods and the associated swivels and lock nuts - dark phosphate?

UPC M20, Sec A7, Page 328, 4 Speed Trans Interlock Linkage (reverse lock out):
Items 2 & 6, the Upper and Lower Rods – phosphate or natural?
Items 3 & 5, the Control Lock Idler #3955780 & Mounting-Support #3945595 – silver cad, zink dark silver or natural steel?
Item 4 (2) screws #9419402 - dark phosphate, E head markings?

Thanks in advance for you input.

The Hurst shifter tower is silver cad, the mounting bracket on a SB car is silver cad, dark gray phosphate on the BB mounting bracket.  Shift levers for 1-2, 3-4 are yellow zinc, the reverse lever is dk gray phosphate.  Shift linkage rods are dk gray phosphate, bell crank is dk gray phosphate,

Thanks Jerry.

Are the shift rod swivels dark gray phosphate also?

I assume the nuts that lock the swivels in place are standard gray-black phosphate?

I am still wondering what the correct finish should be on the clutch push rod assembly.  This is Item #17 & #18 on page 112 in the 69 Assy Manual.  Is it dark gray phosphate also?  See pic attached, the item shown in the bottom of the picture.

Thanks,

Jerry what is the finish on the reverse lock rods and the lock out itself----the part that attaches to the sub frame?

Thanks

I am reviving this thread as there are a few unanswered questions.  I recently purchased a 22,000 original mile 1969 RS/Z project and it appears the engine, transmission and diff have never been out of the car. The car did have a few Day 2 bolt ons including a flex fan, ACCEL large format coil, headers, traction bars and a Hurst Competition Plus shifter body.  The shifter rods and levers that were included with the aftermarket Hurst Shifter assembly were in a box of parts that accompanied the car and were never installed. Instead, the original levers and rods were used, except the long reverse lockout lever to bellcrank rod had been removed (fortunately it was in a box of parts retained with the car).  I have attempted to summarize the information on finishes/plating posted to this thread however the items in bold have not been well defined or confirmed, so input would be appreciated:

1. 3138 Shifter Body - Silver Cadmium
2. Shifter Rods (all) - Zinc (dark grey) Phosphate
3. Reverse Lockout Bellcrank - Zinc Phosphate
4. Reverse Lockout Bellcrank to Subframe Bolts - Manganese (black) Phosphate?
5. Shifter Body to Transmission Adaptor Plate - Sliver Cadmium
6. Shifter Levers 1-2 and 3-4 - Yellow Zinc (or Cadmium?)
7. 5769 Shifter Lever - Reverse - Zinc Phosphate
8. Shifter Lever to Rod Washers - Silver Cadmium  
9. Adaptor Plate to Transmission Bolts (2) - Manganese Phosphate or Silver Cadmium ?
10. Adaptor Plate to Transmission Large Screw - Silver Cadmium (?)
11. Shifter Body to Adaptor Plate Bolts and Washers (2 x 2) - Manganese Phosphate ?
12. Shifter Rod to Shifter Body Lever (threaded) Buckle - Silver Cadmium or Zinc Phosphate ?

Regarding Item 6 (Shifter Levers 1-2 and 3-4) I have never seen these levers in other than Silver Zinc. I understand later production Z/28s may have used Yellow Zinc - would like some input on this . For Item 7 (5769 Shifter Lever - Reverse - Zinc Phosphate), I have only seen the reverse lever in Manganese Phosphate not Zinc Phosphate - would also like input on this.
