  1. Like I said, I know that wasn't how you're supposed to do it, but after a LOT of foul language I decided to focus on the gear that I cared about (D) and see if all the other pieces would just fall into place. Good luck, Nick
  2. We had similar problems when we replaced our C4. For us, it was a misalignment between the detents in the shifter and the detents in the transmission (and of course alignment with the neutral safety switch). I know this isn't the way you're supposed to do it, but what worked for us was... loosen shifter linkage manually put the transmission in drive (count off the clicks) put the shifter in drive tighten the linkage Oh yeah, then fiddle with the neutral safety switch until you can get the car to start in P or N and the reverse lights to come on in R. Hope this helps, Nick
  3. Thanks @Hemikiller! That was perfect. You gave me all the details I need on how to make it look original
  4. This is a great thread everyone! I'm sure all of us have (or will) struggle with this at one time or another. I have a Pertronix III on our 71, but after reading so many horror stories about nuking your tach, I've never had the guts to run it with the tach connected. But reading through this, I have hope. Since the tach is inline and basically a current meter, does it introduce resistance in the ignition circuit? My Pertronix doesn't like anything but full voltage (misses at idles and/or stalls when put in reverse) My motor is an older 302. It doesn't have an anti-dieseling solenoid. Any ideas where I find the wiring for the anti-dieseling solenoid? I have the normal 302 engine wiring harness. Pictures would be great!! Lastly, from what I've read, the Pertronix III (not I or II) is a multi-spark ignition. Doesn't this create extra current pulse that will throw off the tach (read high)? Having @TheRktmn convert my tach is my fallback on getting this all working. At the moment, we don't want to run any new wires into the engine compartment (we're going for the sleeper, factory-looking build).
  5. The convertible and fastback quarters are most assuredly different, but I suspect the detent is the same. I didn't realize NPD had just the bottom part of the quarter. That may be a good way to go too.
  6. I thought of that, but given that it's a compound shape, I have more faith in my welding than my metalworking. On that note, what do I have to lose.
  7. We noticed that the PO of our 1971 Mach 1 must have been in an accident and had the repair done by an absolute idiot. They flattened out the shaped detent for the rear bumper (I do acknowledge my own mental deficiency for not noticing this for 3 years). Anyone have a quarter panel cutout they can part with? Thanks, Nick
  8. Do you still have the oil cap? If so, does it say Autolite or Motorcraft on the top? How much?
  9. I'm trying to figure out the correct shoes and drums for our 1971 Mach 1 w/ 351c. The way I got her from the PO was a mess. She had 4 different size tires, different drums side-to-side, etc. When we replaced the rear brakes, the local auto parts store sold us 1 3/4" x 10 shoes (I didn't know any better then :( ) According to the shop manuals, I think she should have come with 2" shoes, but I've also seen people say it's a crap shoot with what Ford put on the car. My questions: Can put take your pick on installing 1 3/4 or 2 inch (as long as the drums and shoes? I've also heard people say that you can use 2 1/2 with a 2 1/2 inch backing plate. Is that true and/or worth it? Much appreciated, Nick
  10. OMG! Thanks @Hemikiller! This was perfect!
  11. Thanks! I think I have both yokes. Can anyone measure their FMX driveshaft length? Thank you
  12. We got the oem tooling version (I think from CJ Pony Parts, on sale). It fit well and looks like should.
  13. Does anyone know if the driveshaft is the same for a C4 and and FMX behind a 351c (H-code)? Thanks
  14. Hey @Vinnie, please post picture of the work in progress. I have to repair my cowl hat and could use some inspiration. Thanks!
