I'm having trouble understanding?  (I'm slow)

 Are you saying the two missing bolt heads came that way but that bushing has been replaced so no Ford bushings came that way...
"I vote - part of the bushing assembly - (was a) replacement"

OR Are you saying I should deluxe both of these two perches and just replace both bushings?
"I vote - part of the bushing assembly - (needs) replacement"

I'm pretty sure the perches are OEM and I want to replace the bushings and shafts If I can find some that look OEM.

I just looked at the pair of perches I removed from my "K" car and cannot see how the bushing could have been pressed in (or removed) with the two studs in place, eg the studs (or bolts) went in after the bushing was in. Adding that to the mix, if the studs had the serrations, they were pressed in from what would have been the head end but I would think they would pull thru with too much torque on the nuts. Not a good design (what an understatement  :-X ).

Should definitely be bolts installed with the serrated tops.  As long as they're not tack welded to the bushing ends, they come out easy using a bench vise.  The original ones I have seen were cad plated.

I did not know that.  I thought they were phosphate.  Another detail to work on  ::)

The bolt/studs are phosphated or almost natural. The nuts are clear zinc.

I disagree, I have cleaned many originals and found the bolts to be cad plated.  There may have been a couple versions though.

I guess I have too many cars, because I looked at my '66 again and I did replate the perch bolts (zinc, not cadmium, but for convenience or maybe ignorance) when I detailed the front suspension.  They must have had signs of originally being plated.

The image of the perches, page 1 of this thread, from Mike Murray's 4,500 original mile coupe show they are cad/zinc plated.  I went back and looked through my pics and all I could find was originals with silvery plating.  The San Jose 65-66 examples that I have are Rockford stamping on top and fine threads.

Most likely Jim was thinking of the 67-70 perchs which had  zinc phosphate bolts.Been there done that.

I recently removed two sets of the spring perch bolts, one set from my 66 "K" car and the other from 6S19xx. Both cars are San Jose built and the perches were factory. Both cars have been garaged almost from day one, eg minimum road damage. When I dissassemble anything, I look at the condition including finish (credit Jeff). Neither of the two sets' bolts had a trace of cad or zinc, especially the underside of the bolts heads' and the serrations. The only part number I could find for 1964-66 perches was on Ford Car Parts ILL 30 page 04 identifing them as 373134-S, discontinued (aka, not serviced). I measured mine and they are 3/8-24X7/8 hex head grade 8 marked "Rockford". I have no other documentation on this bolt. For 1967, and on including service, Ford used a 3/8-16X1.0 hex head grade 8 marked "C" and "M" (I have two sets on the shelf) identified as 381792-S2 (see AMK Ford Fasteners page 121 and Ford Car Parts Sec 30 pg 24). When I replace the spring perchs on 64-66 Mustangs, I replace the 3/8-16 bolts with 3/8-24 bolts.
Those are my observations.

Think it's safe to say that both finishes were possible.  Probably related to time of production and/or assembly plant.

MAR 1966 C-Code Metuchen.  Did the OEM perches have pads for the spring to sit on at the bottom, or was it metal-to-metal?

I bought a new set from the Ford dealer parts counter around 1984 and I remember they had thick rubber rectangular pads glued on there.

No pads, that was a later thing and later service replacement thing.
