I have also been attempting to gather all the 6 cylinder linkage parts. The main issue is no 6 cylinder Z bar is reproduced. I have sourced one for same in south Carolina, but he wants a lot of money for the condition of the part. There is also a company that makes a clutch cable that works for 6 cylinders:
https://mustangsteve.com/product/clutch-cable-conversion-65-mustang/ This kit will require welding to the bell housing though. The part number seems to bring up 8 cylinder Z bars though? Here was a helpful comparison for all the 65-66 Z bars:
Also here is a thread that I made on Vintage-Mustang forum that was very helpful to me:
https://www.vintage-mustang.com/threads/anyone-know-anything-about-z-bars.1207590/#post-10729650
I am also personally going to an early model yard this weekend to find my own Z bar for my T5 conversion. If I find 2 of the correct Z bars there I can snag one for you and ship it to you if you would like. I can also put you in contact with the person in South Carolina who has one.
Also about the spring, I think I know which one your talking about, but the only reproduction springs I can find are these:
Connects from the firewall to the top of its equalizer bar Replaces the rusted or missing return spring to keep the clutch working properly Made with durable, quality tested materials.

This website has a lot of repo linkage parts. I have no ordered anything from them yet but I plan to as soon as I get my Z bar.
Good luck and let me know if you have any other questions.
Thank you
akidwithacar, for that above Picture I can tell you that sure looks to be the correct 1965 Ford Mustang Equalizer Bar Ford Part #C5ZZ-7528-A on the far left since it has the Swivel Block on it for the Clutch Rod the first of 2 1966 Z Bars for those (built before 2/14/66) also will have that Swivel Block but the last 1966 Z Bar made for (for those built 2/14/66 and after) don't have that Swivel but the 6 Cylinder Z Bar is basically the same one other than that same difference. If I had the measurements from it I could make a new one or even convert a V8 Z Bar by lengthening the center section to the Six Cylinder Length they are a very simple part. I know all the Tube Length measurements of the various V8 Z Bar's but have not found out the measurement of those for the 170 & 200 Six roughly they are about 2 to 2 3/4 inches longer than some of the V8 Bars since the 170 & 200 Six engines setting in the chassis are that much narrower than were the 260 or 289 V8's. Yes I also found that too when I was searching for the 1965 Six Cylinder Z Bars Part #C5ZZ-7528-A, and the two 1966 200 Six Cylinder Z Bars Part #C6ZZ-7528-A, or Part #C6ZZ-7528-D Z Bar the Part Numbers are Right out of the Ford Parts Book. But for some reason the online search engines will change the last Letter so that only the V8 Z Bar's will come up after all they all use this same Basic Part # number except for the last letter will I.D. or is changed for the engine application. Edited to fix the Links!
Here is the Clutch Linkage Part Number Info that I found from the Ford Mustang Parts book
The 1965 Mustang's (including what some call 1964 ½'s) with either a 170 or 200 Six used these Z Bar Numbers and A,B, & F Clutch Rod Numbers. The 1964 or 1965 Falcon and Comet Parts are probably the same parts too I don't have their Parts Book yet. The V8 Z Bars measure from about 6 1/2 to 6 7/8 Inches Long depending on if it' s a Hi Po or not and are from 2 to 2 ¾ inches too short to use with the 170 & 200 Six that are around 8 ½ to 9 inches long. There are 2 1966 Ford Mustangs Z Bar used on is the same as the 1965 and the last one is a little different on the Clutch Rod hook up.
For the 1965 170 & 200 Sixes they used the #C5ZZ-7528-A, Clutch Equalizer Bar (Z Bar). This Z Bar used the –A- Rod Part #C5AZ-7521-E, that is 13 ¼ Inches Long. Plus the B Rod used is Part #C2OZ-7521-A it is 15 ¼ Inches Long. And also the –F- Rod Part #C5ZZ-7521-A that is 16 Inches Long. All these Rod Part #'s are also the exact same Part # Rods that were used on the V8 Model’s. so many are easy to find.
For the 1966 200 Six Z Bar they used the Part #C6ZZ-7528-A, Clutch Equalizer Bar (Z Bar) for those models that were built before 2/14/66. This Z Bar also used the same –A- Rod Part #C5AZ-7521-E as above that is 13 ¼ Inches Long. The –B- Rod used was Part #C6OZ-7521-C is 13 1/8 Inches Long. The -F- Rod used is Part Part #C6ZZ-7521-C is 13 ½ Inches Long. The –A- & -B- Rods are the same Rods as are used on the 1966 V8 Model’s the –F- Rod is a Six Cylinder only Part #.
1966 200 Six Z Bar used the #C6ZZ-7528-D if built after 2/14/66. This Z Bar also used the same–A- Rod #C5AZ-7521-E it is 13 ¼ Inches Long. The same –B- Rod #C6OZ-7521-C is 13 1/8 Inches Long. The -F- Rod used is #C6ZZ-7521-C is 13 ½ Inches Long it is a Six Cylinder only part #. The -A-& –B- Rods are the same Rods as are used on the V8 Model’s
Since I am using the C6 Larger Bell Housing along with the Larger Flat type Fly Wheel I need to also use the 9 inch Clutch Assembly see example below.

The Z Bar for 1965 Mustang for a 170 or 200 Six is Part #C5ZZ-7528-A, the Z Bars for the 1966 200 Six C6ZZ-7528-A, C6ZZ-7528-D Z Bar should also fit. But note that 1966 Part #C6ZZ-7528-D Z Bar will use different Rod Numbers.
These should be about all the parts needed to get a working Clutch Pedal System and Linkage when changing over from an Auto Trans. Below is a decent Video showing how to rebuild Clutch and Brake Pedal Assembly and also showing what parts you will need if you want to do a change over from an Auto Trans to a Manual Trans.
