    72' Rag joint replacement inquiry

    I've seen many guys use a u-joint in place of that rag joint, but I'm not sure how that a would feel while driving. I think the u-jont would defnitely hold up better, but it may also transmit more road noise and feel (not really a bad thing though) to the steering column (and steering wheel) as...

    Vehicles For Sale 1972 Q code 351 4V Cobra Jet

    Georgeous color. If I didn't already have too many "toys" I would make you an offer. My wife would have a fit over me buying another 70's muscle car.

    Beautiful car! But I can honestly say that it looks much better with the Magnum 500's on it than those black wheels that were on it in the first several pics. I was never a big fan of the black wheels on anything as it seems to be a thing for the "millenials". Both of my teenage sons have always...

    71 A Pillar cover LH, FB

    I appreciate the additional pics, but I can see that yours is damaged in that same area as mine is so I think I will pass. It doesn't make any sense for me to buy another one that is just like the one I have already. But again, thank you.

    71 Mach 1 paint color choice help

    I agree that white is everywhere. It seems that on new cars, SUV's and pick-up trucks, white and silver are "the" standard colors anymore. My company buys nothing but white cargo vans and pick-up trucks for our business and that's because they are are more readily available than any other color...

    Seat upholstery question

    Thank you. The added height was the only thing I did not like about the upholstery. But they are very comfortable. I seemed to struggle more reupholstering the seat part of the rear seat. The back part of the rear seat was quite easy. I had to wait for a very sunny 80+ degree day and let the...

    You can hook up each one of the LED Bulbs to a 9-Volt battery to test them. The attached diagram shows which side of the bulb needs to be connected to positive 12-Volts.

    Seat upholstery question

    Several months ago, I purchased the TMI Sport-II seat upholstery from NPD for my 73 Mach-1, which is also code GA. The Sport-II from TMI has the increased bolster thickness on the seat and the back. It is nearly identical to the factory upholstery except for the fact that the padding that I had...

    Did you have to replace your front fenders on your 73 in order to use that 71 chrome bumper? I thought of doing that on my 73 but I was under teh impression that in order to do so, I had to use 71 (or maybe 72) front fenders .

    Will 15x8 Repop magnum 500s fit on all four corners of our cars?

    I put 15x8's (4.5" backspace) all the way around on mine. P245/60R15's on front and P275/60R15's on the rear with no rubbing anywhere. I also replaced my sagging 4-leafs on the rear with a set of Scott Drake 5-leafs (195 Lb. spring rate) and I love the way it rides now and its stance looks good...

    Still trying to determine my engine

    Those look like they are the later 66.1cc closed chamber heads.\ according to the D1AE-GA casting number. Those were the same head castings that were used on the 1971 Boss 351 motor except that the Boss 351 heads were modified with adjustable rocker arms, etc. for use with the mechanical cam and...

    71-73 Seat Track Extensions

    Does anyone know if seat track extensions are available from any manufacturer? I recently reupholstered the interior of my 73 Mach-1 and use TMI's Sport-II upholstery which has increased side bolsters on the front bucket seats and also uses thicker foam padding. The problem now is that due to...

    Will 15x8 Repop magnum 500s fit on all four corners of our cars?

    I have 15x8 Magnum 500's on my 73 Mach-1 with 4-1/2" backspacing. I run P245/60R15's Cooper Cobra's on the front and P275/60R15's on the rear. I have no rubbing issues but the front tires come very close (like 1/8") to the the lowest part of the front fender wheel opening in front of the tire...

    Suspension upgrade recommendations

    After tiring of seeing the rear end of my 73 Mach-1 drooping so much from worn out leaf springs, I installed a set of Scott Drake (#C5ZZ-5560-HD) 5-leaf rear springs which I purchased from Summit Racing. According to the specs on Summit they have a 195 Lb. spring rate and I love them (see...

    Q Code ‘73 Mach 1

    I have a very similar Mach-1 but mine is 4-speed Toploader. I purchased it in 2020 after searching forever for a nice, reasonably priced 69 Mach-1 and fell in love with this "big nose" body style. I've had to do a little bit of of work to it but I absolutely love driving my nearly 50 year old...
