Hi there, after exploring in different directions, I still have some vibrations in the drivetrain. The vibration is rpm-related, not speed-related. So I can for the most exclude the driveshaft, axles an tires. A strong suspect goes way to the transmission, flexplate, torque converter. I have a...

Hi guys and fellow horsemen, a few weeks ago, I saw the nice autumn colors in the woods and took the Mach 1 for a spin out there. The canon cam on the passenger seat, I looked for nice photo locations. I found some nice colorful leaf beds southwest of Hamburg, germany and used the opportunity...

Hi everyone, a while ago I have wired the electric choke of my Edelbrock carb to the switched 12V of the ignition switch. Means the choke heats when the ignition comes on. This works, but if you leave the ignition on for some seconds, the choke begins to heat and to open. It is no problem when...

Hi guys, I reinstalled the FMX into my Mach 1 about a year ago and I guess I mismatched the relationship of torque converter and flexplate when bolting them together (at least, is there a given relationship at all and does it matter?). I feel a slight vibration when revving up. Can the TQ be...

Hi there, Today, I had my 71 Mach 1 out on the streets after a 4 year restoration. Got me a temporary registration. The road test was a disappointment. The front end alignment is far from perfect the Mallory ignition module toasted while starting up. I installed my spare distributor. Mostly...

Hi and a happy new year to everyone! I just got some new 71-73 bright repro fender lip mouldings on ebay for a nice bargain price. I clamped one of them for test fit to the front wheel opening and noticed that the horizontal moulding on the Mach 1 fender interferes with it. Now I wonder...

Hi, I just saw this on the Dynacorn page. No more used cowl clip hunting on graveyards! The whole metal upper and lower shell including air funnels is now reproduced. Although it is the version for non-A/C cars, I am sure it can be easily modified for use on A/C Mustangs. 2 years too late for...

Hi guys, now that I had all electrics back in the car up, tested and running after restoration and re-installation of the harness, since yeaterday the horns are not working any more. Before they worked as they should. I did not check the circuits yet, but the first thing I am about to check is...

Hi guys, I have bought a burtex trunk mat from ACC for my Mach 1. The mat was originally not available for the Mach from the factory, but i think it was for the Grande Coupe. Since this stuff is very protective for the trunk floor, I chose the higher quality burtex mat over the cheaper vinyl...

For spare tire purposes, I need a 15x6 standard Ford steel wheel like it was used on millions of 70s FoMoCo products. 5 x 4,5 bolt circle. Should be straight with no dings or heavy rust. Slight rust or dirt is okay, it will be media blasted an painted new. To keep shipping cost down, offers...

Hi guys, a week ago I bought new disc brake rotors from ACDelco (Durastop). Before installing them on the car, I installed them on a spindle on the workbench and measured them with a dial gauge for runout, etc. Ford specifies a max. lateral runout of 0.003 inch for the 71 Mustang. The ACDelco...

Hi guys, when I got my Mach 1, the belts were not installed in the car, but clattering around in the trunk. They were in bad condition and now, close to the finishing line of the restoration, I had them completely re-webbed and tested in an aircraft belt workshop. I am a bit confused how to...

Hi, after disassembling the rearend of my 71 Mach 1, I found a nick on the sealing surface of the passenger side axle shaft. It is the longer one. It seems someone damaged it when trying to remove the bearing.:@ My axle is a stock original 9 inch, 28 spline, non-locking. If someone has a nice...

Hi guys, I am fingering around with this chrome wire thingy I found in the glove box of my 71 Mach 1 when I got the car. I wonder what its purpose is and how it is used. Someone told me it had to do with the seat belts.

Hi, some time ago, I got my new repro rear bumper (a taiwan part) because the original was rusted, bent and dinged. I was really surprised that the repro part had a nicer chrome than the original, but material was thinner. Otherwise it looks good, fit and sit were quite okay with the exception...

Today I tried to install two new rubber bumpers on the frame rails over the rear axle. The whole receptacle was media blasted, cleaned and painted with chassis black urethane. Prior to installation, I coated the upper part of the rubber slightly with vaseline and tried to press them in by hand...

Hi guys, I am just installing the seats in my Mach 1. When I bought the car, there were no seat track plates to separate the tracks from the carpeting. I was told the cars had them from about 67 to 73, so i bought some. What is the exact purpose of these plates? a.) adjustment of seat tilt...

Hi guys, I am just doing the adjustments on the ignition switch on my 71 Mach 1 and I would like to know if the position OFF does have any electrical function regarding power for accessories. Or do the electrics and accessories of the car only come alive when ignition is switched to RUN and...

Hi guys, I recently bought an aftermarket retrofit delay wiper switch (see image) for 71-73 Mustangs. Since this is a plug-and-play device, there are no special secrets in installing it. Maybe aside from pinning the ground strap to the right point of the dash... I installed it on my 71 Mach 1...

Hi everybody, unfortunately, I can not remember whether there was a seal between the wiper pivots and the sheetmetal when I took the car apart. There is no such part in the catalogs of the suppliers for the 71, so I assume the was none. Right? Michael
