    Yella Terra rocker arm failure

    I am glad this topic was posted, to include the manufacturer's response. Guess who is not going to be on my short list for valve train components when I begin to do an engine build? Burning a fellow enthusiast is just as bad as burning me. Sure, warranty expired. But, it sure looks like a...

    Is it NASA or NACA?

    Our window sticker and other says, "NASA." I use the NACA and NASA interchangeably. My preference is to us NACA, but do not mind when someone "corrects me." Unfortunately I am out of town, and unable to share a copy of the window sticker showing a NASA hood on our 73 Mach 1, but that is...

    Water pump issue

    Be sure to check the heater hoses, and especially the bypasws hose. Those bypass hoses are very rarely chaged unless they begin to leak because they can be a real PITA to change. It is possible yours is leaking and shooting its stream into the rear of the water pump pulley. IMHO, the heater...

    Parts Wanted Buyer Beware

    I do not use PayPal with the family & friends no fee service, unless I truly know the other person personally. If a seller asks for me to use family & friends to save them the processing fee I tell them I will pay the additional fee. If I am asked to use family & friends anyway I look...

    Mach 1 questions

    Our 73 Mach 1 had rust issues that was deep under the trim of the windshield and rear glass. We did/could not see it before buying it, although we did see some "surface rust" on the hood and the lower rear corners of the door panels. In order to properly correct the additional corrosion there...

    Factory looking aftermarket radio

    The more I drive our vintage ponies the more happy I am with their exhaust sounds. I doubt I will ever want to use the radios in them, ever again. The 69 Shelby GT had an oem.factory installed AM, but the prior owner swapped in a period correct AM/FM unit. I still have the original AM radio...

    Vacuum hose routing

    The 1973 Shop Manual for Emission Control (Volume 6) from Forel did not include two vacuum calibrations. They were for the 1973 351 4v engine calibrations, of course. Somewhere along the way I came across both of them, and added them to my Shop Manual pdf file, and kept copies of both the...

    What is this?

    Just a Heads up, the 73 Mustang electric choke for the oem carburetor was fed by Circuit #4 (White with Black Stripe), which is fed by the alternator stator terminal. The electrical output from the stator terminal on the alternator provides current that is not like any other circuits' current...

    Alternator replacement

    Lynda (Mustang Chick & wife) came up with a clever approach in applying muscle to get a belt tight for a hard to reach accessory. To help me put tension on a power steering pump, and later an alternator, whe brought over a few feet of nylon rope. I (after listening to her) looped the rope...

    Owned for 37 years and getting ready to pass it down.

    Scion over a vintage Mustang? My son made it known that if the day ever came when I would be dispensing our pony cars to he and his siblings, he was calling dibs on the 73 Mach 1. That was about 4 years ago. More recently he asked if he could change to the 69 Shelby GT500. heh heh... I told...

    More ripoff tactics from Speedmaster / ProComp Electronics / AT Racing World

    I have purchased parts from Summit in the past, and it was always a good experience. Given how they decided to handle this situation they can be assured of being given the first opportunity to provide parts I need. Kudos to them.

    Rear Power Window socket wiring

    I do have the 1971 electrical schematic for Mustangs/Cougars. But, I can assure you using the 1972 or 1973 schematic will be far easier and understand. I have attached the relevant pages from the 71 and 73 schematic in the attached file snippets. I hope these are helpful. Sorry, no photos of...

    Grande GT?

    I truly appreciate it when folks want to talk about cars, either in general or specifically Mustangs and/or Shelbys. I even have to restrain myself when some Car Show Experts come up to me with one or more of our pony cars and begin to tell me things I know to be inaccurate. Depending on the...

    Any good 71-2-3 Mustang books ever published

    I have heard about that particular style Mustang. But, never learned much beyond the hushed whispers I over heard from time to time. I would love to see some actual photos of one. Perhaps it is time for "me" to do some serious digging, now that you have ressurected the subject. heh heh
