Topic: upper control arm details

I concur.  But for these pair, like the Tootsie Pop, the world may never know.  But we can keep our eyes peeled for some that have a known heritage.

My guess is they are 1966 Fairlane upper arms .......

Interesting. Any evidence that 66 Fairlane UCAs are dimensionally the same as 67-69 mustangs?

[70cj428]

I'm almost certain 66-67 Fairlane and 67-70 Mustang use the same upper arm.  The Dorman replacement arm also fits Mustang and Fairlane (DORMAN Part # 520105)

I think Ford also serviced them all with a 75 Granada number.... (D5DZ 3082-C )

Something to look into....

We all realize by now MANY parts made by Ford fit MANY applications besides just Mustangs (YES, FORD did actually sell other cars besides just MUSTANGS!) The more we understand interchangeability of parts, the easier it is for us to locate some of those hard-to-find items. Junkyards dating back to the 1950's got new books every year to assist them. NOW, it is all computerized. SOME of that information is available to the general public for FREE, if you know how to go about it.

Go to Car-Part.com and look up a 67 Mustang, Control Arm, UPPER...Car-Part.com inventory system is based on the Hollander books. ITEMS SHOWN ( in various salvage yard's inventory across the country or region) WILL BE A DIRECT INTERCHANGE BASED UPON THE LATEST INFORMATION GIVEN HOLLANDER BY FORD.  This does not mean they are THE EXACT SAME, it only means that superceded numbering updates have been applied to allow a more complete interchangeability.

Hollander interchange that these salvage yards use often have A,B,C,D... suffixes along with notes on any interchange. The Car-Parts link I mentioned above does NOT list those A,B,C items withing the listings. You can call a salvage yard and ask them though, or better yet, stop in and they might be willing to show you the interchange and the NOTES.  Granada's UCA, for example,  might be a number such as 511-12345C and 70 Mustang 3-rivet a 511-12345B and your 67-69 Mustang + 66-70 Fairlane/Falcon a 511-12345A.  NOTES might say something like B fits A but has ____ different. or B fits A but A does not fit B.

Am I CLEAR AS MUD YET?

From the dead sea scrolls (Ford Car Parts, May 75, sec30 pg7 & , the replacement upper A arm for a 67 thru 72 (listing end at 72), part number D0OZ-3082-A is the replacing item. This item also fits 66 to 71 Fairlane, 70-72 Maverick and 66-70 Falcon. It is the 3 bolt pattern ball joint type which replaces the 4 bolt ball joint type. That means to count the ball joint mounting bolts first. The 3 bolt ball joint was implemented in 1970, but the upper arm might have been changed.

Thanks for the replies.  But let's put this in time perspective.  I propose that given the various clues on the control arms, they are 66 or 67 vintage.  Certainly no later. 

The 67 only MPC from Jan 67 lists C7OZ-3082-A as for vehicles B, F, and X.  Fairlane, Mustang, and Falcon.  Of course, we need to consider Cougar and Comet.

Correlating the data with the 75 MPC expands the possibilities to the 66 Fairlane and Falcon (and Mercury equivalents)

I suspect that these particular control arms are from one of the 66 models.

Not what I was hoping for, but the control arms themselves are a direct match from what I can see and are free of pits (hard to find here in MI).

It is interesting that there is green paint on the spring saddle - I'll have to see if both sides have that.

John, The C6OZ-3082-B is likely the arm you have. The C6OZ-3082-B used the C4 boot on ball joint.

I was tearing apart some of my UCAs and wanted to add some measurements to the discussion. This applies only to factory control arms.

65-66
Length : Center line of pivot to BJ ball center line : 9 1/2"
Width of frame at pivot center line : 8 15/16"
Center to center, bolts at shock tower : 3 3/4"


67 (and up)
Length : Center line of pivot to BJ ball center line : 9 1/2"
Width of frame at pivot center line : 9 3/4"
Center to center, bolts at shock tower : 4 3/4"

At a glance, the 65-66 frames have one kink (a sharp cornered change of direction) in the outside, flat part of the frame with the one kink at the spring pivot bolt.
67-up have two kinks. One as noted above (65-66) and another quite near, but before, the inner pivot.

So while they are the same length, they are not the same width (in the frame or pivot).
