 Made quite a bit of progress on parts over the last few weeks.  Including some before and after pictures.  Rear brake hose before,

Rear brake hose retainer to body bracket, note the"P", which is barely visible when installed.  

 Extension that attaches to the rear axle housing.  Note :"W" logo on the before pic.  Also, note how the original plating tended to be heavier around the edges, just like it came out after reconditioning and re-plating below.

This shows original paint daub on the rear brake hose...

On the other side there was a bunch of orange paint smeared along the length of the hose.  Never seen this before.

And here is the complete reconditioned hose assembly, no paint daubs added yet.

 Here is the backside of the brake hose to body bracket.  Looks like raw steel plate with cosmoline originally.

Here's where the bracket was attached behind the rear seat in the kick-up area in front of the axle...note that the underside of the car was painted black before this was installed.  Also, note how crudely the holes were drilled that attached the bracket to the body.  On every K code I've seen this bracket is welded in place, but on this car, the holes were drilled during the process of fitting the exhaust system on the car.  This bracket had to be located so that the brake hose would not interfere with the exhaust driver side pipe in the newly fabricated dual exhaust system.  In fact, you can see that the holes on the floor pan were drilled before the inner reinforcing plate was installed - you can see the reinforcing plate the enlarged holes in the floor pan.

Here is a view from the inside of the car showing the two bolts on the right that held the bracket in place.  To the left of those bolts are the two cadmium finished bolts that held the driver side exhaust bracket in place.  Later cars used a special bracket that had both bolts attached instead of two separate ones.  You can tell that there was never a bracket here.

These bolts will be reused as is, just cleaned up.  Again preserving as it was when the car was assembled the first time.

Here are the lower control arm to body bolts, lock washers, and nuts.  Also the original rear leaf spring forward attaching washers.

 Lower control arm fasteners after cleaning and re-plating.  Turned out awesome.  Note head markings, these are not reproduced.

Another cool part, these  are the before and after pictures of the front stabilizer to lower control arm extensions.  These are the sleeves with "FM" stamped into them, presumably for "Ford Motor" company.   Prevailing belief is that these sleeves were natural steel with phosphate/oil finish and that the bolts were also phosphate and oil with a blank head.  On this car, the bolts were marked "rockford" on the head, and the sleeves were clear/blues zinc.  The refinished parts turned out true to the original.

 Note how the original rubber insulators were marked with blue paint...have seen this on other early Hipo's.

Restored upper fender attaching bolts.

 Rear wheel cylinder with original paint daubs.  Both left and right rears were marked with orange and white...

...whereas the fronts were marked with black and orange.  This is totally different than the makings seen on other restored K codes.  These original markings will be preserved.

 Restored original motor mounts.  The finish turned out even better than i had hoped.  there was a blue spray painted spot on the drivers side mount that over sprayed on the lower cross-member that will be recreated at assembly time.

Rear shock to axle plate with original paint daub.

 After  restoration.

 Transverse muffler stamping.  Only 5-64 stamped dual exhaust transverse muffler I have ever seen.  Most NOS units are stamped 10-64.

Markings on front spindle.

 Orange paint daubs were used to locate the outer parking brake brackets.  There were many places on the car where orange paint was used for identification of parts specific to the K code.  Why these were marked is unclear since they are identical to non-hipo mustangs of the production period.  It may be that these too were fitted in place as part of the dual exhaust fitting process, as they determine the amount of parking brake cable held in place between the frame rails.

 Oddly, the inner parking brake cable brackets were painted black while the outers were natural steel.

 The original Ford assembly team scraped off the fresh under coating where the outer parking brake cable brackets would mount.  Note orange paint underneath.

Although you can't tell from the picture, some of this is rust dust that came out when the forward leaf spring bolts were removed.  The rest is orange paint.

These wires on the parking brake cables were a 64 1/2 Dearborn tool for keeping the cable out of the way during chassis assembly.

 Unbelievably, all of the original 64 1/2 dual exhaust brackets were still on the car.  The goofy spot weld on the upper left bracket was used on the installation of new resonators installed by the owner prior to me (I have the receipt).  These will all be refurbished and reused - possibly the first set of Mustang dual exhaust hangers, used during the hand-fitting of the new exhaust system to the car.
