OMG....Literally the same story here!!!!!!!!!!!!!!! I'm sure you know this and appreciate the car beyond what one can convey here..... despite what we all see on the TV car shows & mags.... original or semi-original muscle cars will always be of immense value and desire....not that they can't be modded but as long as it is easily returnable to the original state. The gold air cleaner as stated was most likely factory....but Dad may have come across one that was given to him by someone who was going to put a oval cobra style air cleaner on one and back in the days, no one kept those...most ended up in the trash! The orange valve covers...I bet if you can remove the top layer of paint, you'll find the original color underneath....
Something to remember....
Up through the 60's & early 70's, vehicles were not ordered as they aretoday. Yes, if you ordered package "X" it would come with 1, 2,3.....but, you could also delete specific items within the package. As anexample, our mustang (which has been in the family since it was new), whenordered as a GT, my parents really didn't like "trumpet tips" throughthe rear pan so the dual exhaust was a "delete" (as shown on theoriginal order papers which we still have) and upon delivery, it was off to themuffler shop for a set of pipes.......a very common practice- which because ofthis it is not impossible, but I will say it is much more"challenging" to not so much verify something is a factory GT byhaving all of the items listed, but more difficult to verify it is not..andFord was not the only one doing this either, a very common practice by the Big3.
Dealers also dealt with qualitycontrol issues....and had a pre-approved budget by the mfg's to effectrepairs....there are documented stories and pics where mustangs were deliveredto the dealers with the trunk lids wrapped and sitting in the backseat....Customers could also pay an additional fee (typically $300) for thedealer to "special prep" the car prior to customer delivery...whileeach had a different name they called it...basically the dealer had the mech'sgo through the cars from nose to tail checking every single part, fit &finish...making it right. These cars typically looked, ran like fine tunedmachines as a result...you could see, feel the difference.
My neighbor worked for GM inLong Beach, Ca back in the 70's, and clearly recalls special order deletes,hand carried orders to install "X" cylinder head on a particular car-he also recalls there was seldom more than a week went by that the cylinderheads didn't change (as far as port matching/sizing/shape)- as it was alldependent on the supplier and that varied by each shipment….or someone wantedtheir pickup painted the color that was offered on a particular car…..not aproblem as long as it was built at the same plant (for an extra charge ofcourse)- which also explains a few very, very unique ID plates.
While it is a wonderful thing to have a variety of people who have done suchexhaustive research on these and other vehicles, we must also remember that thecustomer service and deliverables of the time were much, much different thantoday and paperwork, was, well, not the focus. This has lead to benefit us(especially in Calif) who became exempted from smog testing/cert because of theabsence (disposal/non-retention) of documentation of our cars, but in allreality, even if all the paperwork did exist, it wouldn't do little to validatemuch more than is known today about the cars- because the paperwork was not apriority, delivering what the customer wanted was.
There were also 4 HiPo 289’s….the common (HiPo) 271 hp, and the 306 hp availableonly in the GT350R, producing 350 horsepower, weighed 75 fewer pounds, andfeatured an enlarged fuel tank (34 gallon vs. 18) for racing. With “specialheads”, a super-duty suspension, racing tires and more, it was offered in 1965only......just an FYI
With regards to part suppliers..... I'm betting you guys have done most all of your own maintenance work and if you have a need, I have maintained an e-list of every parts supplier we have ever used (family has a racing history going back to the 40's). If you ever need brakes for the car...I highly recommend CarboTech….(I have used these on every vehicle we have since the 80's when VelvaTouch was pulled off the market)……. and VelvaTouch is what our Mustang came with....
The linings run about $200 a pair but are well worth it both in wear, cleanliness and "bite" (braking co-efficient- .49)...I can and have demo'd hitting the brakes at almost 100 mph (private road) and the car stopped effectively and straight as a dime (4 wheel drum brakes).
