I'm glad that there are sources for NOS parts, but you really have to pay attention and know what you're supposed to be getting because they don't seem to have a clue. Both of my NOS wheel cylinders arrived yesterday from different vendors. Neither is correct.

One doesn't even look like an original Ford part (Wagner instead of Bendix or Kelsey Hayes) and no paint codes to identify which side and what diameter. All the other NOS wheel cylinders I've seen have 2 paint daubs to identify them (size and handedness). It was also missing one of the pistons, so it wasn't even useable.

Fortunately they gave me a refund without any hassle. The other one was a genuine NOS Ford part with the expected paint code marks, but it was an "acceptable substitute" or "interchanges with" part (C4UZ instead of C5TZ). It would bolt in place, has the correct handedness, the hose would screw right in and the pistons are the correct diameter. However, if all I wanted was a suitable substitute I could get that from Rock Auto and save some money. I'm willing to pay for NOS parts because they're supposed to be the EXACT part that it would have come from factory.

I have a couple of options: I could hone out the original cylinders or drill and tap a pair of NOS Mustang wheel cylinders to use the truck brake hose. For now I think I'll just leave it alone and go with the aftermarket wheel cylinders already installed. Bummer.

 

I know what you are saying. I have purchased many of supposed NOS parts. One of the biggest was a '66 F-100 Brake Booster. I paid Big $$ for it only to find inside the box was the "core".

Pretty sure I have the NOS wheel cylinders for a F-100. Front or rear? Have shocks and a bunch of other stuff I have been hoarding. Planned on doing a 100% correct truck but time and age are getting the better of me.

I have NOS Brake shoes too. I spent 1/2 a fortune on NOS 1966 F-100 Parts.. One was a front bumper still in a wrapper and wooden shipping box. Paid really big $$ for it about 17 yrs ago now & still have it. Went to pull it out of package around 6 months ago only to find its a C4tZ bumper but 67-72 replacement. Paid well over 500 for it too. Now I cannot get the price for a junk aftermarket for it and its still in the wrapper. Same guy I bought the NOS booster from and also a NOS A/C compressor. Compressor cap where fittings are was broken. I found out later he would purchase NOS parts then put a used or broken item back in box, slip it back on ebay and play dumb after the fact. I had well over 1000.00 wrapped up in the parts with ZERO refund.

 

Sorry to hear your story Boss9! My dad has always told me "stop feelin' sorry for yourself, there's always someone who has it worse than you". And that would be you right now Boss9.

I'm not looking for '66 F100 front wheel cylinders, I was trying to go up a size to 1 1/8" The C5TZ 2061/62 parts would have the larger bore size and also have the small 1/4" bleed valve like my originals. I have new reproduction rears with the 1/4" bleed screw and I wanted to make them all the same.

I often consider the lessons I learn from buying unusable junk on ebay just the price of a higher education. I do hate taking the same class over and over again though.

 

C5TZ-2061-C (replaced C4UZ-2061-A) Right & (EDIT) C5TZ-2062-C (replaced C4UZ-2062-A) Left .. Front Wheel Cylinders - 1 1/8" diameter / Obsolete

1964/67 E100 with 10" x 2 1/2" brakes; 1968/71 F100 with 11" x 3" brakes.
-------------------------------------------------------------------------------------
1965/67 F100 2WD use different wheel cylinders:

C5TZ-2061-A Right & C3OZ-2062-C Left .. Front Wheel Cylinders - 1 1/16" diameter / Obsolete

C5TZ-2061-A = 1965 F100 4WD & 1965/67 F100 2WD w/11" x 2" brakes.

C3OZ-2062-C = 1965 F100 4WD w/11" x 2" brakes; 1965/67 F100 2WD w/11" x 2" brakes; 1963/65 Fairlane with 10" x 2 1/2" brakes.

 

NOS does not mean that they are the parts installed at the factory. It is new old stock, literally a new part from old stock. That means it is possible that it is the same part that was installed at the factory, but it can also be a genuine replacement that was made available, say in the '80s, which may or may not be identical to the original.

In the case of using the original part number when it is clearly a replacement part number, that is dishonest and should not have happened.

However, a genuine replacement part is probably better than the Chinese part you would get brand new from everywhere now.

 

NOS = New Old Stock genuine OEM (Original Equipment Manufacturer: Ford/GM/Chrysler etc.) obsolete parts.

NORS = New Old Replacement Stock obsolete parts...sold by auto parts stores.

Obsolete parts: From 1966 thru 1985, I bought out over 300 west coast FoMoCo dealers, former Studebaker and/or Packard dealers, 2 Chevy dealers and a former Desoto/Dodge dealer.

The best money makers: Former Packard dealer in Watsonville and a L/M dealer in Yuba City.

 

Yes there are 2 different part numbers and I think you meant C5TZ 2062-C for the RH side. I was specifically trying to go up to the 1 1/8" bore size while keeping the original appearance with the 1/4" (wrench) bleed valve.


One vendor sent me what was supposed to be an AD 2061-A part in a red and white box, but what was in the box was obviously aftermarket, not an OEM Ford part at all.


The other vendor sent me the C4UZ interchange part that's basically what I already have installed (larger 3/8 wrench size bleed valve). It was at least a genuine Ford sourced replacement part.


I'm also aware that NOS doesn't always mean assembly line correct, but it does have to at least be an original Ford sourced replacement part to qualify, and when I specify a part number, I'm really looking for THAT part number, not what interchanges with it.

 

C3OZ-2062-C .. 1 1/16" is what the 1964/72 Ford Truck Parts Catalog lists for the left front wheel cylinder for: 1965 F100 4WD & 1965/66 F100 2WD with 11" x 2" brakes.

The right side is C5TZ-2061-A

See EDIT in post 4: C5TZ-2062-C (replaced C4UZ-2062-A) .. Left Front Wheel Cylinder - 1 1/8" diameter = 1964/67 E100 with 10" x 2 1/2" brakes; 1968/71 F100 with 11" x 3" brakes.

This parts catalog is available on a C/D from hipoparts.com

 

I didn't see your edit in post 4. I have the parts catalog, that's how I found the part numbers for the 68-71 HD 3" front brake wheel cylinders. I've also swapped the backing plates and installed new 3" front shoes (ceramic matrix) and drums.

 

EDIT: Typed several minutes ago when I realized I had typo'd C5TZ-2061-C for the 1 1/8" diameter left side instead of C5TZ-2062-C

C5TZ-2061-C is the right side.

C5TZ-2061-A; C3OZ-2062-C; C5TZ-2061-C/C5TZ-2062-C listed here: Text Section 20.1, Parts List #2 .. page 8.
